Mean median, mode, and range
Mean, median, mode, and range are common measures used in statistics to describe the central tendency and variability of a data set.
The mean is the average of a set of numbers calculated by adding all values and dividing by the total number of values.
The median is the middle value in a sorted list of numbers or the average of the two middle values if there is an even number of values.
The mode is the value that appears most frequently in a data set.
The range is the difference between the smallest and largest values in a data set, representing the spread or variability.
