Pie Chart & Bar Graph
200
A variable that is a measurable value, i.e. always a number
What is a quantitative variable?
200
Girls have no outliers, while boys have an outlier of 40 pairs of shoes
What is comparing outliers
200
This graph has a tail going to the right.
What is right skewed?
300
What quantitative display of data has the a column showing the shared tens value on one side of a line, and each data point's ones value on the other side of the line?
What is a stem plot?
300
You always need to the x (and if present the y) axis for all graphs
What is LABEL?
300
A variable that assigns an individual to a group, i.e. usually a word answer
What is a categorical variable?
300
"Both distributions are skewed right, but the girl's has a longer tail"
What is comparing shape?
300
The left and right sides of this graph appear mirrored.
What is symmetric?
400
In a stemplot showing age of gym members, what does the value
5 l 6
likely mean?
What is 56 years old?
400
Why should you never use pictures, images, or 3D bars to represent data on bar graphs?
Using any of these makes the differences look exaggerated (or not proportional)
400
Identify the variables within this chart as categorical or quantitative.
What is 2 categorical variables and 4 quantitative variables?
400
"The standard deviation of the girl's shoe pairs is larger than boys, so the girl's data is more spread out."
What is comparing variability
400
In this distribution the mean is greater than the median.
What is right skewed?

500
Identify the types of variables within this chart.
What is one categorical variable and two quantitative variables?
500
Both graphs are symmetric, but the girl's data has a wider curve
