What does each 'x' represent in a line plot?

Back

Each 'x' represents one occurrence of a data point.

Front

What is a statistical question?

Back

A statistical question anticipates variability in the data and can be answered by collecting data.

Front

How do you read a histogram?

Back

To read a histogram, look at the height of each bar to determine the frequency of data within each interval.
