Broken line graph• A broken line graph shows data by plotting the

data points with dots that connect into a line.

Double stem plotA double stem plot graph compares two pieces of data with the same stem in the middle

Line plot

• A sketch of data in which marks above a labeled line to show how many times a number is used

Maximum

• The biggest number in the set of dataEx 1:1,2,3,4,5,6,7,8,9,10 10 is the biggest

number in the dataEx 2: 2,4,6,8,10,12,14,16 16 is the biggest

number in the data

Median

The middle number in a set of data when it’s lined up lowest to highest

• Ex 1: 1,2,3,4,5,6,7,8,9,10,11- 6 is the median or middle number of the data

• Ex 2: 2,4,6,8,10,12,14,16,18,20,22 - 12 is the median or middle number in the data

Minimum

• The smallest number of the dataEx 1: 1,2,3,4,5,6,7,8,9,10 1 Is the smallest

number of the dataEx 2:2,4,6,8,10,12,14,16 2 is the smallest

number of the data

Mode

• The most repeated number of the dataEx 1: 1,2,3,4,5,5,5,6,7,8,9,10 -5 is the mode or

the most repeated number of the dataEx 2: 2,2,2,4,6,8,10,10,12,14 -2 is the mode or

the most repeated number of the data

Mystery plot• A unlabeled graph or plot

Random Sample

• A sample that gives everyone a chance of being selected to be part of the data

Sector

• A region together by an arc and two radii of a circle, sector also has the name of wedge.

Stacked bar graph

• A bar graph where the bar is divided into smaller parts to show portions of a whole group

•

Step Graph• A graph that looks like steps because the data

steps up or steps down.
