(middle number)
What is the median?
Upper quartile. The median of the upper half of data.
What is Q3?
How spread out the data is.
What is variability?
Organizes data values into equal-size intervals of the number line.
What is a histogram?
Data values that are much less or much greater than the other data values.
What is an outlier?
The distance between the lower quartile and upper quartile.
What is the IQR? (inter quartile range)
Lower quartile. The median of the lower half of data.
