The students will study measures of center this week. We will have a test over the measures of center on Friday. The measures of center are mean, median, mode, and range. The students need to know how to solve for the measures of center.
Mean add all the numbers and divide by how my number you add
Median put the numbers in order from least to greatest. Mark off one number on both sides ( low and high) repeat till you get to the middle number. If 2 numbers are in the center add the 2 numbers and divide by 2.
Mode the number that repeats the most
Range subtract the minimal value from the maximum value.
