Question

For the given data {1, 2, 2, 3, 4, 7, 9}, match the measures of central tendency.

• A. 2
• B. 3
• C. 4

Answer 1

{1, 2, 2, 3, 4, 7, 9}

$Mean=\frac{Sumofallobservations}{Numberofobservations}$

$=\frac{(1+2+2+3+4+7+9)}{7}$
$=4$

Median is the middle most value in the arranged data set. Here the value of the median is 3, as it falls exactly in the middle.

Mode is the most repeated value. Here except 2 all the values are there for one time. The value of the mode is 2.
