Measures of central tendency are used to Indicate and describe the central position of a group of data. These measures are
important because they help you condense data, find representative values, make

The three measures of central tendency are mean, median, and mode.
Mean (often referred to as average) is the sum of all values divided by the number of
values in the dataset.
Median Is the middle value that separates the higher half from the lower half of a dataset.
Mode Is the value in a dataset that appears most frequently.
It is the most popular measure of central tendency It uses every data point in its calculation. Mean is calculated using the following
because formula:
Mean=Sum of All Values/Number of All Values
