The mean and median are both measures of center, each appropriate with different types of data. When would each be appropriate and why?
Mean is the best measure of central tendency.
But mean is highly affected by the presence of extreme values.
In that case median will serve the purpose.

MODULE 5. MEASURES OF CENTER 40 Module 5.1 A Feel for Measures of Center Learning Goal: For the distribution of a quantitative variable, describe the overall pattern (shape, center, and spread) and striking deviations from the pattern. Specific Learning Objectives: Find the mean and median from different representations of data. Develop number sense with mean and median by creating different data sets with a given mean or median. 1) Here are two sets of exam scores, one for a class...
Find the means. The mean for systolic is__ mm Hg and the mean for diastolic is__ mm Hg. (Type integers or decimals rounded to one decimal place asneeded.) Find the medians. The median for systolic is___ mm Hg and the median for diastolic is___mm Hg. (Type integers or decimals rounded to one decimal place asneeded.) Compare the results. Choose the correct answer below. A. The mean is lower for the diastolic pressure, but the median is lower for the systolic...
