What does the lower quartile (Q1) represent?

Back

The lower quartile (Q1) is the value that separates the lowest 25% of the data from the rest.

What is the median in a dataset?

How do you find the median of an even set of numbers?

For an even set of numbers, the median is the average of the two middle numbers.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1). It measures the spread of the middle 50% of the data.

Front

How do you calculate the IQR?

Back

IQR = Q3 - Q1.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

What does a box plot visually represent?

Back

A box plot visually represents the distribution of data based on a five-number summary: minimum, Q1, median, Q3, and maximum.

Front

What is the purpose of a box plot?

Back

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