Q62 2017, Elementary Algebra

If for a sample data Mean < Median < Mode then the distribution is

Arithmetic mean is also known as average. It is the sum of all the numbers divided by the number of numbers.

Median is the middle value in the list of numbers written in ascending or descending order.

A Normal Distribution is perfectly symmetrical (not skewed). It means Mean = Mode = Median.

A distribution is skewed if one tail is longer than another. These distributions are sometimes called asymmetric distributions. These are of two types:

1. If Mode < Mean, then the data is skewed to the right.

2. If Mode > Mean, then the data is skewed to the left.
