Inferential Statistics and Findings

This paper shows the information that is needed to get the correct inferential statistics information. The research question and mock data will help ensure that the research project is going in the right direction. The confidence interval level helps to ensure that the research project is will go between two values that a population factor will fall between.

The Research Question

The research question is: Is there a relationship between the frequency of drinking coffee (DV) and the customer experience rating? We will select 100 coffee drinkers in three different cities to show the relationship between the frequency of drinking coffee and the customer experience rating.

Mock Data For The Dependent And Independent Variables

The dependent variable would be the coffee drinkers. The independent variable would be the frequency of drinking coffee and the amount of customers that were satisfied. There are 1,035 coffee drinks that had been surveyed through the week. There are 100 coffee drinkers that were surveyed in a week. The average amount of cups the average customer drinks in a week is 10.35 cups. The mode or the most cup of coffee a customer drinks is 21cups of coffee. The median is eight cups per customers. The standard deviation is 7.663 with a 95% confidence level which shows how much the individual interpretations may fluctuate much from the group. Using a 95% confidence interval level was -4.699. The parameter lies within -4.699.

The customer coffee experience rating sum is 345. The total amount of people surveyed was 100. The average or the mean of the survey was 3.45. The median or middle of the number is 4. The mode or most common of the numbers is 4. The standard deviation is .925 which shows how much the individual ratings that the customers may vary much from the group. Using a 95% confidence interval level was 1.637. The parameter lies within 1.637.

Conclusion

The research question gave a good starting point for the research plan. The mock data gave enough information to be able to be able to show how inferential statistics can show if the project the data is correct. This paper will help with finishing the research project in the final week.
