Question

It is not necessary to sort observations before finding median and percentiles.

a. True
b. False

Answer 1

False - It is necessary to sort observations before finding the median and percentiles.

Step-by-step explanation:

False - It is necessary to sort observations before finding the median and percentiles.

When calculating the median, you need to arrange the numbers in order from smallest to largest. The median is the middle value if the data set has an odd number of observations, or the average of the two middle values if the data set has an even number of observations.

Percentiles also require sorting the data. Percentiles divide the data set into equal parts, so you need to know the order of the observations to determine the desired percentile.
