Learning Target: Estimate the mean and median from a histogram

Warm Up: p. 91 #4 a and b

Goals:
• Go over the MIQ
• Work on Investigation 2 calendar work with your group

HW: Finish the Investigation 2 calendar work your group decided on.

Reminder: L1I2 MIQ tomorrow. Be able to complete a problem like what’s in the investigation. In order to retake the MIQ, make sure you have completed everything from the ENTIRE row labeled Investigation 2 including all the investigation work and the MIQ practice problem.

Reflection: The formula for finding the position of the median is (n+1)/2. That means you get a position and count up the data points until you get to that position. That number is your median. For example, if the number of values is 9 then the position of the median is (9+1)/2 which is 5. Then count up the data set until you reach the 5th value. If the data set is: 5, 7, 9, 11, 14, 22, 32, 33, 44, then the median is 14.
