What does the upper quartile (Q3) represent in a Box and Whisker Plot?

Back

The upper quartile (Q3) represents the value below which 75% of the data falls.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the upper quartile (Q3) and the lower quartile (Q1), representing the middle 50% of the data.

Front

How do you find the median of a dataset?

Front

How can you identify outliers in a Box and Whisker Plot?

Back

Outliers can be identified as points that fall outside 1.5 times the IQR above Q3 or below Q1.

Front

What percent of the data lies between the lower quartile and the upper quartile?

Back

50% of the data lies between the lower quartile (Q1) and the upper quartile (Q3).
