3、cessary to know more information about the market.In this report,the software of SPSS will be used to analyze the data and statistical methods will be interpreted in the case.Introduction Michael Jenkins is going to operate his own restaurant and he asked the research film to conduct a survey.The pu

4、rpose of the survey was to explore more information to verify the probability of the success in his restaurant and then giving some useful information to help him make decisions.The report will analyze the market influence factors and use statistical methods such as uni-variate,bi-variate and multi-

5、variate to make the data more meaningful.At the end,some recommendations based on the analysis result will be given.Methods of analysis Data analysis should be different in different problems(Pallant,2010).In this the procedure of the data analysis,the approach of the data analysis include as below.

6、The descriptive statistic is a brief description of the characteristics of the data,such as mean,variance and others.The independent sample T test is one of the uni-variate analyses.This test method is applicable to the assumption o f the population whose distribution is normal,population variance i

7、s unknown(Larson,2010).And this test is used to distinguish the difference of the mean between the sample and the population.The paired samples test is one of the bi-variate analyses.The test judged whether two related samples are from the same population and it also assumed that the distribution is

8、 normal.Through comparing the significance of the statistics t of the different samples,the difference between two samples can be seen.The independent test has the same principle as the paired samples.However,it is 5 used when two samples are independent from each other.And the result lies in the si

9、gnificance of the statistics t.The single factor of variance test is used when the variate is more than two.And it is the foundation of the analysis of variance.The theory of the method is to study the degree of a factor affected by other factors and see whether the results are significant.Pearson c

10、orrelation is analyzed to see the simple correlation between two factors and find the potential meaning(Luo,2011).Analysis of the each question Because the sample size is large,so assume that is a normal distribution(Yang.2011).Hypothesis1.The cost that people desire to pay for a meal is no more tha

11、n the calculated value of$19.The null hypothesis is like the subtitle upside.The alternative hypothesis is that the average amount is not less than the forecast value.We use the descriptive statistics and then get the following result as the table 1.Table 1 the average meal to be priced According to

12、 the table,we can see that the mean is 19.23 more than 19,so reject the null hypothesis.Hypothesis2.The average revenue of the people surveyed is different from$70,000.6 Choose the null hypothesis as the average income is$70,000 and the alternative hypothesis is not equal to$70,000.Because this is o

13、ne sample,so the one-sample test is used.Table2 One-Sample TestFrom the table 2 we can see that the statistic value of t is 4.905,the degree of the freedom is 399,the 95%confidence interval is(4247,9927)and the confidence level of the statistic t is 0.000,so reject the null hypothesis and we think t

14、he mean of the people surveyed in the revenue is different from$70,000.And the value is$77,087.50 that is significant.Hypothesis3.The preference degree for simple d cor is equal to the degree of elegant d cor.Choose the null hypothesis as the preference for the two samples are the same and the alter

15、native hypothesis is the two are not equal.The mean of the two choices for the simple and elegant are 2.26 and 3.64.Because this is the preference related to one person,which means the two samples are related,so the paired sample test is used.Table 3 Paired Samples Correlations N Correlation Sig.Pai

16、r 1 The Preference for Simple Decor&Elegant Decor 400.838.000 From the table3 we can see that the statistic value of correlation is o.838,and the confidence level of the correlation test is 0.000,so the two samples have tight relationship with each other.Table 4 Paired Samples Test 7 From the table

17、4 we can see that the statistic value of t is-40.398,the degree of the freedom is 399,and the confidence level of the statistic t is 0.000,so the null hypothesis should be rejected and we think the difference between the two samples is significant.Figure 1 Figure 2 8 Based on the chart above,we coul

18、d know that nearly 16.5%of the respondents feel preference for the simpled cor,60.75%of the respondents feel preference for the elegant d cor,so the elegant one is preferred.Hypothesis4.Different marital status of people spent differently in the mean number in restaurants each month.The null hypothe

19、sis could be that different marital status for the two samples are the same in the mean amount spent and the alternative hypothesis is the two are different.Because this is three kind of marital status with the amount spent in restaurants and we want to know the certain dependent variable,so the sin

20、gle factor analysis of variance is used.Table 5 ANOVA 9 From the table 5,we can see that the statistic value of F is 99.939,and the confidence level of the statistic t is 0.000,so reject the null hypothesis and we think the difference between the three kinds of marital status is significant.Figure 3

21、 We can know the mean of different form of the marital status from figure 3.The mean amount spend for the married is higher than the other.It is 232.6,so it is the category that spends most.Hypothesis5.Mean preference for jazz combo=the average preference for string quartet.Choose the null hypothesi

22、s as the mean preference for the two samples are the same and the alternative hypothesis is the two are not equal.The mean of the preference for jazz and string are 2.40 and 3.39.Because this is the preference related to one person,which means the two samples are related,so the paired sample test is

23、 used.Table 6 Paired Samples Correlations N Correlation Sig.Pair 1 Prefer Jazz Combo&Prefer String Quartet 400.885.000 10 From the table6 we can see that the statistic value of correlation is o.885,and the confidence level of the correlation test is 0.000,so the two samples have tight relationship w

24、ith each other.Table 7 Paired Samples Test From the table 7 we can see that the statistic value of t is-33.469,the degree of the freedom is 399,and the confidence level of the statistic t is 0.000,so we should accept the alternative hypothesis and we think the difference between the two samples is s

25、ignificant.Figure 4 Figure 5 11 Based on the chart above,we could know that nearly 60%of the respondents feel preference for the string combo,35%of the respondents feel preference for the jazz combo,so the string one is preferred.Hypothesis6.The probability of attending and the part of the newspaper

26、 that is read by people have a relationship with each other.The null hypothesis is no association between the variate and the alternative hypothesis is association.We choose the Pearson correlation test.Table 8 Correlations It is obviously the correlation between the two is weak,the value is only-0.

27、023,and the confidence level is not significant.12 Table 9Frequency Percent Valid Percent Cumulative Percent Valid Editorial 104 12.3 26.0 26.0 Business 112 13.2 28.0 54.0 Local 94 11.1 23.5 77.5 Classifieds 90 10.6 22.5 100.0 Total 400 47.2 100.0 Missing System 448 52.8 Total 848 100.0 The frequenc

28、y analysis of the section indicates that the business part of the newspaper is a better choice for advertising,it accounts for 13.2%and the frequency is 112.Hypothesis7.Different postcodes have different tendency to pay for a meal in the average spending.The null hypothesis is no difference between

29、the A,B,C,D postcodes and the average money people paid for a meal and,the alternative hypothesis is different.Due to this is four kinds of postcodes with the average price people are more likely to spend on a meal and we want to know the certain dependent variable,so the single factor analysis of v

30、ariance is used.Table10 ANOVA From the table 10,we can see that the statistic value of F is 3.099,and the confidence level of the statistic t is 0.027,so reject the null hypothesis and we think the difference between the four kinds of postcodes is significant.Figure 6 13 We can know the mean of diff

31、erent form of the postcodes from figure 6.The average price people are willing to pay for a meal for the postcode B is higher than the other.It is 20.75,so it is the category that on average is willing to pay most.hypothesis8.The male average monthly expenditure in the restaurant is quite different

32、from the female.The null hypothesis is no difference for male and female in the average restaurant expenditure in a month and the alternative hypothesis is different.Due to the genders are two styles such as male and female,and each of the two are independent,so the independent samples test is used.

33、From the table 11,we can see that the statistic value of t is-2.98,and the confidence level of the statistic t is 0.003,so reject the null hypothesis and we think the difference between the two kinds of genders is significant.And the mean of different form of the genders is$202.16 and$213.96.The fem

34、ale expenditure in a month in the restaurant is higher than the male.It is 213.96,so female is willing to pay most.14 Table 11 Independent Samples Test Hypothesis9.Total expenditure people spend in the restaurant is connected with the income people get.The null hypothesis is no association between t

35、he variate and the alternative 15 hypothesis is the total expenditure has a connection with the income people get.We choose the Pearson correlation test.Table 12 Pearson correlation test What is your annual salary?How many total dollars do you spend per month in restaurants(for your meals only)?Pear

36、son Correlation 1.134*Sig.(2-tailed).007 N 400 400 It is obviously the correlation between the two is weak,the value is only0.134,and the confidence level is significant.The nature of this relationship is that they have a positive correlation.Hypothesis10.Theaverage value of people spend on food eac

37、h month can be described by the average cost people are desiring to spend on the meals,age,gender and income The null hypothesis is that they can be explained and the alternative hypothesis is not.Figure7 Figure8 16 Figure 9 According to the figure7,8,9,we can see that there is weak positive correla

38、tion with the income and gender,and negative correlation with age.Summary and Recommendations Through the marketing research,we know more information about the market.We use the data which have been collected in the research and use statistical methods such as the independent sample T test which is

39、one of the uni-variate analyses,paired sample T test,single factor of variance and so on.Every question has two hypotheses,one is null hypothesis and the other is alternative hypothesis.The train of thought is to make assumptions and use the statistical methods to test whether the null hypothesis sh

40、ould be rejected.Through analyzing,the result will tell the difference between two or more factors and whether the variables we are choosing are independent or dependent.We will make sure the reality and the environment of the market in the way of making 17 the questions quantitative.And on the beha

41、lf of each result that SPSS exported,several reasonable suggestions will be given.We can draw the suggestions as below:Firstly,according to the result that SPSS has exported,there is a great demand for the elegant restaurant,and people are willing to pay more than$19,people s revenue is higher than$

42、70,000,the elegant style of the restaurant will be popular in the future,so this is a chance for Michael Jenkins to be a successful business man.Secondly,the restaurant should pay attention to construct the sweet family atmosphere and female diet characteristics,play more string combo,and then use t

43、he postcode B.In the end,what should be maintained is that they must improve to care to all level of the crowd.Reference Pallant,J.(2010).SPSS survival manual:A step by step guide to data analysis using SPSS:Open University Press.Larson.P.(2010).Elementary statistics(fourth edition).China Renmin University Press Luo.L.(2011)data analysis w ith spss,qinghua university press Yang.w.(2011)Statistical analysis and application in SPSS.qinghua university press
