Today we used this data to learn how to find the median. The median is the middle value in a set of data. It is VERY important to put the data in order from smallest to largest in order to find the median.
First, we identified the shortest and longest jumps in our class. Each child wrote their jump on a small slate. Then we lined up accross the room from smallest to largest jump. Once we confirmed that the line was in order, we asked the shortest and longest to step out of line. We continued this process until we were left with two students in the middle. They represented the median.
Although we did this in class, children may need more guidance at home to find the median. The set of data MUST be put in order from smallest to largest in order to find the median. If they do not order the numbers, they will be unsuccessful in finding the median.
Please refer to the "Family Note" at the top of the homework page. It states...
"...arrange the data in order from smallest to largest. Count from either end to the number in the middle. The middle value is the median."
