Finding Mean, Median, and Mode

What is the definition of the mean?

• The middle number after the numbers have been put in order from least to greatest.

• It is computed by summing all the values of the variable in the data set divided by the number of observations.

• The number that occurs the most often.

• The difference between the highest and lowest numbers.

What is the definition of Median?

• The number that occurs the most often.

• It is computed by summing up all the values of the variable in the data set divided by the number of observation.

• The difference between the highest and lowest numbers.

• The middle number after the numbers have been put in order from least to greatest.

What is the definition of mode?

• It is computed by summing all the values of the variable in the data set divided by the number of observations.

• The difference between the highest and lowest numbers.

• The number that occurs the most often.

• The middle number after the numbers have been put in order from least to greatest.

When finding the median, what do you do if there are two middle numbers?

• Pick one

• Just pick them both

• Add them together and divide by 2

• Add them together

What is the first thing you should do before finding the median or the mode?

• Arrange the numbers in order from least to greatest.

• List the number how they are.

• Start croosing numbers off.

• Look for repeats.
