7.1 Data Displays & Their Shape

Front

What is a symmetric distribution?

Back

A symmetric distribution is a type of distribution where the left side is a mirror image of the right side, often represented by a bell-shaped curve. In this distribution, the mean, median, and mode are all equal.

In a symmetric distribution, what is the relationship between the mean and median?

Back

In a symmetric distribution, the mean is equal to the median.

Front

What does it mean for a data set to be skewed left?

Back

A left-skewed data set has a longer tail on the left side, meaning that most data points are concentrated on the right.

Front

What does it mean for a data set to be skewed right?

Back

A right-skewed data set has a longer tail on the right side, meaning that most data points are concentrated on the left.

Front

What is a box and whisker plot?

Back

A box and whisker plot is a graphical representation of a data set that shows its minimum, first quartile, median, third quartile, and maximum.

Front

How can you describe a right-skewed histogram?

Back

A right-skewed histogram has a longer tail on the right side, indicating that there are a few high values that pull the mean to the right.

Front

What is the mode of a data set?

Back

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

Front

What is the median of a data set?

Back

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

Front

What is the mean of a data set?

Back

The mean is the average of all the values in a data set, calculated by dividing the sum of the values by the number of values.

Front

What does it mean for a distribution to be uniform?

Back

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