c). Describe a measure of central tendency for quantitative data that can be used for two of the four levels of measurement (and say which of the two levels of measurement are).

d). Describe which measures of center & variation are influenced by outliers.

Answer 1

a) The mean and the median can only calculate the quantitative data, while the mode can calculate both the quantitative data and qualitative data.

b) Measure of central tendency used for three of the four levels : Average Level of measurement: Ordianl, interval and ratio

c) Measure of central tendency that can be used for two of the four levels: Median Level of measurement: Ordianl and interval levels

d) measures of center & variation are influenced by outliers are mean and variance respectively
