Question

The values that divide a set of numbers into quarters is

• A. whiskers
• B. median
• C. quartiles
• D. none of the above

Answer 1

The correct option is C quartiles

Quartiles are the set of values which has three points dividing the data set into four identical parts.

Example: Let's consider a data sample below:
$1,3,4,7,9$

The middle part of the three quarters $\left(4\right)$ measures the central point of distribution, which is called as median.

The lower part of the quarters $(1,3)$ indicates just half information set which comes under the median$\left(4\right).$ Median of $(1,3)$ is called the lower quartile.

The upper part of the quarters $(7,9)$ shows the remaining half, which falls over the median. Median of $(7,9)$ is called the upper quartile.

The maximum$\left(9\right)$ and minimum$\left(1\right)$ values are the extremes of the data.

Overall, the quartiles represent the distribution of the data.
