It is always 50%
It represents the largest part
It represents zero
If 50% of a pie graph is shaded, that means…
All of the data
Half of the data

Which bin has the most

A histogram has the tallest bar at 80–89. What does that mean?

80–89 is the lowest range
Every value is exactly 80
Most data values are in the 80–89 range
If most dots are close together, the data is probably…
Missing
Clustered
A pie graph
Impossible
What does a pie graph show?

A dot plot has dots at 2, 3, 3, 4, 9. What do you notice?
9 may be an outlier
The data has no numbers
2 is the largest number
All numbers are the same
Why is a dot plot helpful?
It only shows percentages
