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.

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.

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.
