Purpose
The purpose of this project is to assess your ability to:
Collect and display data.
Use Excel.
Calculate and interpret expected value.
Calculate the mean, media, and mode of data sets.
Determine whether data sets are normally distributed.
Apply the Central Limit Theorem.
Summarize and report findings.
OVERVIEW
This module you will turn in the third part of Project 2. This project consists of three parts.
Project 2-1: Identify the Distribution of a Sample – due in Module 9
Project 2-2: Find A Sampling Distribution of Sample Means – due in Module 10
Project 2-3: Final Submission – due in Module 11
Data that follows a normal distribution pattern is predictable and can be used to draw conclusions. However, many data sets do not follow a normal distribution pattern, and a small sample may not follow the normal distribution even if it comes from a normally distributed population. The Central Limit Theorem tells us that the distribution of sample means will not only be normally distributed, but also, if we have enough samples, the sampling distribution will have a mean that is approximately the same as 𝜇, and a standard deviation that is close to 𝜎𝑛.
To see this, let’s continue the experiment using sets of randomly generated integers.
ACTION ITEMS
Open your saved Excel file as submitted for Part 2.
Review your gradebook feedback and make any required corrections to Parts 1 or 2.
Complete the tab labeled “Part 3 – Calculate” by using Excel formulas to do the following:Calculate the mean and standard deviation for each of the 4 data sets from Parts 1 and 2.
Calculate the expected standard deviation of the sampling distribution of the sample means.Note, you may either calculate these directly on this tab using cell references, or calculate these using formulas on your original sheets and copy/paste the values into the designated area of the calculation sheet.
Explain how your graphs tables and calculations of the mean and standard deviations relate to the Central Limit Theorem.

This criterion is linked to a Learning OutcomePart 1: Random generation of 100 integersGenerate 100 integers randomly using =INT(RAND()*(10)).
Count the frequencies using =countif( and verify the frequency table.
Create a table consisting of expected frequencies and sample(actual) frequencies.
Create a bar chart of the actual frequencies.
Create the expected frequencies (uniform) graph.
5 to >4.0 ptsOne hundred integers were randomly generated correctly using formulas in Excel. The frequencies of each integer (both expected and actual (sample)) are correctly represented in the frequency table. The bar charts of frequencies (both expected and actual (sample)) are accurate. The bar charts have an appropriate title and the axis labels and the x-axis are correct. Improvements were made based on feedback, if applicable.
4 to >2.0 ptsOne hundred (or fewer) integers were randomly generated using formulas in Excel. The frequencies of each integer may not be correctly represented in the frequency table. The bar chart of frequencies may not be accurate. The bar chart may contain errors within the title, axis labels and/or the x-axis. The expected (uniform) bar chart may contain errors. Some improvements may have been made based on feedback.
2 to >0 ptsNo integers were randomly generated or there are major errors in the generation affecting the bar chart and frequency tables. The bar chart, the expected (uniform) graph or frequency table may be missing. Little to no improvements were made based on feedback.
