Median

Line segments connecting vertices and midpoints

If you subtract the lowest number from the biggest, you get the range. The mean, or average, of a set of numbers is found by dividing the sum of the numbers by the amount of numbers added. The middle number when numbers are arranged in order. If there are two middle numbers, the median is the average of the two. The number or numbers that occur most often in a set of numbers is the mode.

This video gives a brief description of a Stem-and-leaf plot, how to make them and use them to find median, range and quartiles.

This lesson is on Means Medians And Modes with a detailed explanation of the topic.

This is a short lesson on Stem and Leaf Plots. It includes a demonstration on how to create and read a stem-and-leaf plot and also how to use it to find Median and Quartiles.

Average refers to the sum of numbers divided by n. Also called the mean average. In this video lesson we will be exploring how to calculate an average.

This lesson shows how to calculate Mean, Median and Mode with some tricks to help remember the differences of these methods of finding the Center.

Average refers to the sum of numbers divided by n. Also called the mean average. In this video lesson we will be exploring how to calculate an average.
