 # Mean, Median and Mode (I) Worksheet and Solutions

Objective: I know how to calculate mean, median and mode.

In statistics, mode, median and mean are typical values to represent a pool of numerical observations. They are calculated from the pool of observations.

Mode is the most common value among the given observations. For example, a person who sells ice creams might want to know which flavor is the most popular.

Median is the middle value, dividing the number of data into 2 halves. In other words, 50% of the observations is below the median and 50% of the observations is above the median.

Mean is the average of all the values. For example, a teacher may want to know the average marks of a test in his class.

Calculate the mean, mode and median of the following sets of data.
Round the mean and median to the nearest tenth when necessary.
If there is no mode, type in the answer “none”
If there are more than one mode, type in the modes separated by a comma and do not have spaces in your answer, for eg. 5,8
