What is a double box plot?

Back

A double box plot is a graphical representation that displays the distribution of two sets of data side by side, allowing for easy comparison of their medians, quartiles, and ranges.

Front

What does IQR stand for?

Back

IQR stands for Interquartile Range, which measures the spread of the middle 50% of a data set.

Front

How do you calculate the IQR?

Back

IQR is calculated by subtracting the lower quartile (Q1) from the upper quartile (Q3): IQR = Q3 - Q1.

Front

What is a quartile?

Back

A quartile is a type of quantile that divides a data set into four equal parts, with each part containing 25% of the data.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of a data set, representing the 25th percentile.

Front

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of a data set, representing the 75th percentile.

Front

What does the median represent in a data set?

Back

The median is the middle value of a data set when it is ordered from least to greatest.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.

Front

How can you identify the median from a box plot?

Back

The median is represented by the line inside the box of a box plot.

Front

What does a box plot show about a data set?

Back

A box plot shows the distribution, central tendency, and variability of a data set, including the median, quartiles, and potential outliers.
