    What is the purpose of developing a frequency distribution? What is the relationship between the relative frequency and the cumulative frequency? Could a frequency distribution contain qualitative data? Why?

    Describe the properties of a normal distribution. Why are there infinite possible normal distributions? Why should one assume that sample data represents a population distribution?

    Does all statistical data have a mean, median, or mode? Why? When is the mean the best measure of central tendency? When is the median the best measure of central tendency?

    What is the purpose of developing a frequency distribution? What is the relationship between the relative frequency and the cumulative frequency? Could a frequency distribution contain qualitative data? Why?

    The frequency distribution gives you a "count" for each category or value. For instance, in a paper I was just writing, I needed to show the reader how many participants worked for each of the four kinds of firms in the study. A bar graph in Excel is a frequency distribution, showing how much in each bar (if you are familiar with this function). It can tell you how many workers are making below $20,000, between $20,000 and $40,000, and above $40,000 by sorting the group into these ranges.

    Relative frequency is the count versus the total. So, for my study, what percent of the participants worked for Auditing firms? 27% of the total (count of 45). That is the relative frequency. Here is the relative frequency for wages:

    Wages below $20,000.................................45%
    Wages between $20,000 and $40,000.....20%
    Wages over ...
