HISTOGRAM
Different parts of the world have experienced catastrophic droughts over the past 10 years. Imagine you are studying the amount of rainfall received over a set period of time in order to help an area find solutions during times of water shortage. You might collect data on rainfall patterns on a monthly basis for a year. Then, chart your data to provide a graphical image of monthly rainfall rates. The resulting histogram indicates a range of rainfall.
This week, you will generate your own histograms using data from the Study Habits dataset provided in the Learning Resources.

- Practice creating histograms using the Quick Guide Data Set “Q55. HISTOGRAM.xlsx” and the Check Your Understanding Data Sets “QS55a” and “QS55b”.
- Choose a continuous variable from the Study Habits dataset and use Excel to create a histogram of this variable. Note: The dataset contains missing data. For this Discussion, do not clean the missing data.
- Review the Working With Datasets Job Aid Download Working With Datasets Job Aid for instructions on “How to Post a Visual Display to the Discussion Board”, as you cannot copy and paste the histogram directly into the Discussion Board.
BY DAY 4 (POST FIRST)
Post your histogram and interpret it in terms of normality. Explain your reasoning. Note: Refer to the Learning Resources for assistance.
