compare and contrast measures of central tendency and measures of variability.

Brief Explanations:

Measures of central tendency (mean, median, mode) describe the center of a data - set. Measures of variability (range, variance, standard deviation) describe how spread out the data is. Central tendency gives an idea of a typical value, while variability shows the dispersion around that typical value. For example, in a class's test scores, the mean score is a central tendency measure, and the standard deviation of scores shows how much the scores vary from the mean.

Answer:

Measures of central tendency represent the center of a data - set (e.g., mean, median, mode), while measures of variability show how spread out the data is (e.g., range, variance, standard deviation).
