What is a box and whisker plot?

Back

A box and whisker plot is a graphical representation of data that shows the distribution's minimum, first quartile, median, third quartile, and maximum values.

Front

How can you determine variability in a box and whisker plot?

Back

Variability can be determined by the length of the whiskers and the interquartile range (IQR); longer whiskers and a larger IQR indicate more variability.

Front

What does a symmetrical distribution look like?

Back

A symmetrical distribution has a mirror image on either side of the center, meaning the left and right sides of the distribution are approximately equal.

Front

What is a skewed left distribution?

Back

A skewed left distribution has a longer tail on the left side, indicating that most data points are concentrated on the right.

Front

What is a bimodal distribution?

Back

A bimodal distribution has two distinct peaks or modes, indicating that there are two prevalent values in the dataset.

Front

What does multimodal mean in the context of a distribution?

Back

Multimodal refers to a distribution that has multiple peaks, indicating several prevalent values or clusters in the data.

Front

What is the interquartile range (IQR)?

Back

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

Front

How do you identify the median in a box and whisker plot?

Back

The median is represented by the line inside the box of the box and whisker plot, dividing the data into two equal halves.

Front

What is the significance of the whiskers in a box and whisker plot?

Back

The whiskers extend from the quartiles to the minimum and maximum values, showing the range of the data outside the interquartile range.

Front

What does it mean if a distribution is described as 'normal'?

Back

A normal distribution is a bell-shaped curve that is symmetrical about the mean, with most data points clustering around the center.
