Statistics is the science of making effective use of numerical data relating to groups of individuals or experiments into a table or a chart.
The main things we will study in the average statistics are:
Mode is the most common value among the given observations. For example, a person who sells ice creams might want to know which flavour 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.
