median
mode
range
interquartile range
mean absolute deviation

Answer 1

mean, median, range, m.a.d

Answer 2

• mean
• median
• range
• Mean absolute deviation

Explanation:

measures of central tendency and variability that are mainly affected by outliers.

Mean : This is the measure of the average of a set of data i.e the summation of data divided by the number of the given data

Median : This is measure of the value in a set of data that divides the set of data into two unequal or equal halves i.e the most centrally placed value in a set of data

Range : the difference between the highest value and the lowest value in a given set of data

Mean absolute deviation: this is the average of the absolute deviation of a given set of data taken form a central point

These measures of central tendencies are affected by outliers while Mode and interquartile range are not affected by outliers.
