In the past two days, we have discussed many of the ground-work that will be utilized later when discussing advanced statistics. We talked about;
1.) Nonparametric and parametric data
2.) Descriptive and inferential statistics
3.) Frequency Distribution
4.) Measures of Central Tendency
5.) Graphic distribution of data
6.) Standard deviation and variance
Question for thought- Generally, when describing the data, we use the mean as our measure of central tendency. For your post, give an example where the mode or median may explain the data better. Explain the variable you are investigating, and give the circumstances why the mean may not tell you information you could obtain from the median or mode.

The median would describe the data better when looking at a class's exams scores. The median works better because it gives a whole number, and since the scores were all around the same thing, and there really were not any extreme outliers, therefore, the information the mean would give is not really necessary.
that previous post was by Krysten Reed #2, sorry guys!!
