What is the median in a data set with an odd number of values?

• The mean of the two middle values

• The most frequently occurring value

• The middle value when data is ordered

• The difference between the highest and lowest values

In a data set with an even number of values, how is the median determined?

• It is the value that appears most frequently

• It is the sum of all values divided by two

• It is the mean of the two middle values when data is ordered

• It is the largest value minus the smallest value

What defines a mode in a data set?

• The value(s) that appear most frequently

• The middle value of the data set

• The average of all data points

• The difference between the highest and lowest values

What happens if every value in a data set occurs with the same frequency?

• The data set has multiple modes

• The mode is the average of all values

• The data set has one mode

• The data set has no mode

How is the range of a data set calculated?

• By counting the number of data points
