How do you calculate the Mean of a data set?

• Add all numbers and divide by the number of numbers

• Arrange the numbers and find the middle one

• Find the number that appears most often

• Subtract the smallest number from the largest number

What does the Median represent in a data set?

• The difference between the highest and lowest values

• The most frequently occurring number

• The middle value of the data set

• The average of the data set

How is the Median found in a data set with an even number of members?

• By subtracting the smallest number from the largest number

• By choosing the number that appears most often

• By selecting the first number

• By finding the average of the two middle numbers

What is the Mode of a data set?

• The average value

• The middle value

• The most frequently occurring value

• The difference between the highest and lowest values

Can a data set have more than one Mode?

• Yes, if multiple values occur with the same highest frequency

• No, because mode is always the middle value

• No, a data set can only have one mode

• Yes, but only in data sets with even numbers
