Module 1

Introduction 

MEAN
The mean of a collection of numbers is their arithmetic average, computed by adding them up and dividing by their number.

MEDIAN
The median is the midpoint in a collection of numbers; half the data values are above the median, and half are below.

MODE
The mode is the most frequently occurring value in a collection of numbers.

Let's calculate mean, median and mode in the following experiment.

There are 9 students in Mrs. Green’s class.

Mrs. Green wants to know the average or mean time it takes them to divide a deck of 52 cards into 2 equal piles each containing 26 cards, regardless of color or suit. Let us calculate this with her. She will use a stopwatch to time the students.
