What is a Stem & leaf Chart?
Maths Term:
A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution. They evolved from Arthur Bowley's work in the early 1900s, and are useful tools in exploratory data analysis.

Median , Range & Mean
What is a Median?
The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.
What is a Range?

Description

In statistics, the range of a set of data is the difference between the largest and smallest values.
What is the Mean?
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest.
