ANALYSIS OF MEANS

posted in: Do my Essay for me Cheap | 0
  1. What is the mean for each (not combined)
  2. A) X7,

For x7, the mean is 4.7, it means that subject moderately agrees that they are have self-confident.

  1. B) X12,

For x12, the mean is 3.8, it means that subject somewhat disagrees that they are friendly employees in their work place.

  1. C) X17,

For x17, the mean is 4.64, it means that subject is undecided whether they like houses whose interior is attractive.

  1. D) X22.

For x22 the mean is 4.9 it means that subject is undecided whether they were satisfied with the services that they have received from the restaurants they attended.

  1. Compare and contrast the means of two groups.  Are males OR females less likely to buy a new product? Explain fully your conclusion.  Don’t guess.  Support your answer by providing the mean that was computed.

The males are likely to go for the new product compare to female counterpart. This true because the male has higher mean of 5.91 compared to the female mean of 5.41. This means that higher number of males are likely to buy a new product whenever a chance avails itself. It can also be seen also that the number of men (208) who participated during this study were also higher compared to that of women (117). 3.  Correlation: Explain fully the concept of correlation between variables.  Based on the questionnaire implemented and the SPSS outputs, does the Pearson Correlation reveal that there is a high or low correlation between the level of satisfaction and the likelihood to return to a favorite Mexican restaurant?  What was the Pearson Correlation computed to be?  For example .4, .6, .73, .85, or 1.0?  Don’t guess.  Explain fully.

The computed Pearson correlation was found to be 1. With such high level of satisfaction, the probability that a person would return was 0.584 for the 325 participants in the research. The significance of the two tailed analysis was 0.000.

  1. What does the multiple regression reveal about the ability of fun, size, taste, and service to predict customer satisfaction?  Don’t guess.  What are the beta coefficients for each?  Explain fully.   

When the place is fun to eat, the probability of being satisfied is 0.082. When the amount of food served is 0.132 while the excellence taste of food contributes to only 0.191 portability of having the customers satisfied. The speed of the services however carries the day where the probability of having a customer satisfied because of the speed of service is 0.292.
