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.
