types of graphs
Graphs & Data enVision Topic 18PA Assessment Anchor M5.E
* bar graph:
compares data
* line graph:
shows change over time
* circle graph:
shows parts of whole
also called pie chart

scale
Graphs & Data enVision Topic 18PA Assessment Anchor M5.E
* series, or group, of numbers
* numbers placed at fixed spots along one of the axis, or lines, of a graph* changing distance between these fixed spots can make data easier to read on graph

interval
Graphs & Data enVision Topic 18PA Assessment Anchor M5.E
* distance between numbers on scale of graph
*separates the distance into equal parts
*difference between 2 numbers next to each other on scale is the interval
interval is 10
interval is 1

mean
Graphs & Data enVision Topic 18PA Assessment Anchor M5.E
* average
* a number that best represents all numbers in a series, or group
* to find average, or mean:
1. add all numbers in series
2. divide that sum by how many numbers are in series

median
Graphs & Data enVision Topic 18PA Assessment Anchor M5.E
* number in the middle of an ORDERED series, or group
* to find median:
1. order numbers from LEAST to GREATEST
2. Cross out numbers on each end until only one number is left
3. number that’s left is median
