What does the maximum value in a box plot represent?

Back

The maximum value in a box plot represents the highest data point in the dataset.

Front

What does the minimum value in a box plot represent?

Back

The minimum value in a box plot represents the lowest data point in the dataset.

Front

What is the median (Q2) in a box plot?

Back

The median (Q2) is the middle value of the dataset when it is ordered from least to greatest.

Front

What are quartiles in a box plot?

Back

Quartiles are values that divide the dataset into four equal parts. Q1 is the first quartile, Q2 is the median, and Q3 is the third quartile.

Front

What is the first quartile (Q1)?

Back

The first quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What is the third quartile (Q3)?

Back

The third quartile (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

How do you find the range of a dataset using a box plot?

Back

The range is found by subtracting the minimum value from the maximum value.

Front

What does the interquartile range (IQR) represent?

Back

The interquartile range (IQR) represents the range of the middle 50% of the data, calculated as Q3 - Q1.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to provide a visual summary of the distribution, central tendency, and variability of a dataset.
