Normal Distribution Project

Collect a set of data and analyze the characteristics of the distribution.

Part 1

Collect a set of data with at least 30 data points. Data should be quantitative.

the heights of a large number of people

the number of pages in a set of books on a bookshelf

the number of hits earned by different professional baseball players in a season

or if you prefer you can use the data below:

Tik Tok videos viewed by a student over 30 days:

7, 11, 6, 8, 8, 10, 7, 6, 13, 7, 6, 9, 11, 8, 14, 8, 5, 8, 6, 12, 3, 10, 8, 5, 9, 4, 9, 10, 12, 7

Part 2

A visual representation of the data. If the data is continuous, use a histogram. If the data is discrete, use a bar graph.

label the axes with appropriate titles and incorporate the appropriate scale on each axis.

Part 3

1. What are the mean and standard deviation of the set of data?

2. Does the data follow a normal distribution?

3.

a. If your sample follows a normal distribution, does this make sense to you? Explain why.

b. If your sample does not follow a normal distribution (e.g., it could be skewed left or right, have a uniform distribution, or

have some other shape), then why might this be the reason?

4. Describe the survey process. What are some sources of possible bias in the sample? Alternatively, how is it a ensured random sample?

5. What set of data would be used in the future ? How can it be ensured as an unbiased random

sample?
