Week 2 Assignment  

Descriptive Statistics

The most important part of statistics is accurately and effectively communicating the results of a study. For this lab, you will be conducting a statistical study of your choosing and reporting out your results.

Lab Procedure:

Think of a topic or question that you’re interested in exploring further that can be studied through data.

It is recommended, but not required, that you pick a topic in your field of study.

Find a source for your data (or use one of the suggested data source sites listed below).

The data must be quantitative and ratio-level (See Chapter 1).

You will need between 30 – 60 data values.

You will need to provide a direct link to the source of the data.

Using Excel, perform the following statistical analyses:

Calculate the relevant and necessary descriptive statistics (See Chapter 2)

Use Excel to generate a frequency histogram (See Chapter 2)

It should be accurate, with the proper number of classes

All axes should be properly labeled

See textbook and Canvas resources for examples of properly formatted histograms

The audience for your article should be the general public. This is an exercise in creating authentic and professional work,

Not just outlining steps you did for an assignment. Write this as it was assigned to you by a supervisor at a new job, not an instructor in a stat class.

As shown in the sample report, yours should include an introduction/background, statistical analysis (both in words and with graphics), and a conclusion based on the analysis.

Your written report should include both a frequency distribution table and the frequency histogram that you created using your data in Excel. (See sample report)

These figures should be titled, formatted, and appropriately sized (see sample report)
