|
The ogive is used to display what type of distribution? |
|
|
Card: 24 / 34
|

|
|
Card: 31 / 34
|
What does a component bar diagram show? |
|
|
Card: 32 / 34
|
A component bar diagram shows both total values and part values of a set of data, with different parts represented in the same order for all bars.  |
|
|
Card: 33 / 34
|
True or False: The median is always the average of the highest and lowest values in a data set. |
|
|
Card: 34 / 34
|
