Data Distributions

Front

What is a box and whisker plot?

Back

A box and whisker plot is a graphical representation of data that shows the distribution of a dataset based on five summary statistics: minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

Front

What does the median represent in a data set?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. It divides the dataset into two equal halves.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the smallest value in the dataset from the largest value.

Front

What is the mode of a dataset?

Back

The mode is the value that appears most frequently in a dataset.

Front

What does it mean if a distribution is skewed left?

Back

A left-skewed distribution has a longer tail on the left side, indicating that there are more lower values in the dataset.

Front

What does it mean if a distribution is skewed right?

Back

A right-skewed distribution has a longer tail on the right side, indicating that there are more higher values in the dataset.

Front

What is a symmetric distribution?

Back

A symmetric distribution is one where the left and right sides of the distribution are mirror images of each other.

Front

What is a uniform distribution?

Back

A uniform distribution is one where all outcomes are equally likely, resulting in a flat shape when graphed.

Front

What is the first quartile (Q1)?

Back

The first quartile (Q1) is the median of the lower half of a 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 a dataset, representing the 75th percentile.
