Front

What is the mean of a data set?

Back

The mean is the average of a data set, calculated by adding all the values together and dividing by the number of values.

Front

How do you find the median in a data set with an odd number of values?

Back

Order the data and find the middle value.

Front

How do you find the median in a data set with an even number of values?

Back

Order the data, add the two middle values, and divide by 2.

Front

What happens to the median if a constant is added to every value in the data set?

Back

The median will increase by that constant.

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 midrange of a data set?

Back

The midrange is calculated by taking the average of the maximum and minimum values in the data set.

Front

What is a weighted mean?

Back

The weighted mean is the average of a data set where each value has a different level of importance or weight.

Front

What does a right-skewed distribution indicate?

Back

A right-skewed distribution indicates that the majority of the data points are concentrated on the left side, with a long tail extending to the right.

Front

What does a bimodal distribution indicate?

Back

A bimodal distribution indicates that there are two different modes or peaks in the frequency of data values.

Front

How does adding a constant to all values in a data set affect the mean?

Back

The mean will increase by that constant.
