Symmetrical and Skewed Data

Front

What is symmetrical data?

Back

Symmetrical data is when the data is evenly distributed around a central point, creating a mirror image on both sides.

Front

What is skewed left data?

Back

Skewed left data is when the majority of the data points are concentrated on the right side, with a long tail extending to the left.

Front

What is skewed right data?

Back

Skewed right data is when the majority of the data points are concentrated on the left side, with a long tail extending to the right.

Front

How can you identify symmetrical data in a graph?

Back

Symmetrical data can be identified by a bell-shaped curve where the left and right sides are approximately equal.

Front

How can you identify skewed left data in a graph?

Back

Skewed left data can be identified by a graph that has a longer tail on the left side and most data points clustered on the right.

Front

How can you identify skewed right data in a graph?

Back

Skewed right data can be identified by a graph that has a longer tail on the right side and most data points clustered on the left.

Front

What is the mean in a symmetrical data set?

Back

In a symmetrical data set, the mean, median, and mode are all equal.

Front

What happens to the mean in skewed left data?

Back

In skewed left data, the mean is typically less than the median.

Front

What happens to the mean in skewed right data?

Back

In skewed right data, the mean is typically greater than the median.

Front

What is the median?

Back

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