Data

Every day information is gathered and presented for analysis.
Many things are learned from this analysis.

Mean is another name for the average.
Median is the midpoint for the data when all numbers are listed and written in number order
Mode is another word for the number that is repeated the most. There can be more than one mode.

Range is the distance between the lowest and the highest number. Subtracting the lower number from the higher number will give you the range.

Information can be presented in many forms - graphs, plots, circles, and pictures.

This can be reviewed by clicking below.

If you had any problems in the past adding, subtracting, multiplying or dividing, go back and review that material.
