# One-way ANOVA analysis

Not what you're looking for?

For this assignment you are to compute inferential statistics (i.e., hypothesis testing) on your two variables and discuss your findings. You need to include your calculation or write-up of your inferential statistics in the paper using a table and a brief discussion. If you calculated your statistics using Excel include both the spreadsheet showing your data along with your statistical calculations. If you do your statistics by hand you must discuss/show/include the actual values used in the calculation in the paper.

Calculate an inferential statistic test (i.e., hypothesis test) using the research question and two variables your learning team developed for the Week 2 Business Research Project Part 1 assignment (i.e., the same research question you have been using for all the team and individual assignments from Week 2). Include the following in your paper:

The research question (you are repeating the research question again for this section)

Mock data for the independent and dependent variables (Your data may have needed to be changed in order to run inferential statistics - you need either one numeric dependent variable and one categorical (i.e., grouping variable such as gender, time period (time 1 and time 2), group 1, group 2, etc.) variable or two numeric variables in order to compute inferential statistics.

Determine the appropriate statistical tool to test the hypothesis based on the research question.

Conduct a hypothesis test with a 95% confidence level, using the statistical tool.

Write an interpretation of no more than 350-words of the results and provide your findings. Were you able to reject or not reject the null hypothesis. What is your conclusion based on rejecting or not rejecting the null hypothesis with respect to your research question?

Introduction

The Grocery Store, which created its name and brand by selling high quality, organic foods is now losing sales and market share to generic store brands that actively seek out the high-quality, low price supplies. In the Week 2 Business Research Project Part 1 assignment, our learning Team A has decided to investigate whether there is a strong relationship between the weekly sales of the Grocery Store and the offering of private label whole/organic ...

- "Your solution, looks excellent. I recognize things from previous chapters. I have seen the standard deviation formula you used to get 5.154. I do understand the Central Limit Theorem needs the sample size (n) to be greater than 30, we have 100. I do understand the sample mean(s) of the population will follow a normal distribution, and that CLT states the sample mean of population is the population (mean), we have 143.74. But when and WHY do we use the standard deviation formula where you got 5.154. WHEN & Why use standard deviation of the sample mean. I don't understand, why don't we simply use the "100" I understand that standard deviation is the square root of variance. I do understand that the variance is the square of the differences of each sample data value minus the mean. But somehow, why not use 100, why use standard deviation of sample mean? Please help explain."
