Measures of Central WHAT?!

"Measures of Central Tendency."

That's math-language for "numbers that show you something about the middle of a data set."

It's not that hard if you know some good strategies.

First, we had to get some data sets. So, we went to the Weight Room. We planned to do curls and the treadmill, but we found out that the treadmill was gone!

We did the curls. We each had a dumbell. It was five pounds. We had 30 seconds. We counted how many curls we could do. We wrote down the data on our notes.

It was not a contest. We just had to get data.

We did five sets. We counted our own curls and Sister Patrice used her phone like a stopwatch.

We could not do walking on a treadmill. Instead we got data about how many times we could toss and catch some large dice in 30 seconds. We had to keep going if we dropped one. We wrote down our count on our data chart. We did five sets each.

We figured out some ways to get a lot more tosses! 

We used clipboards for getting our data.



The next day we used our data. First, we had to listen to a weird song. Some of us thought it was a stupid song. It did help us remember the difference between median, mean, mode and range, though. We glued it into our Handbook for Adulthood.

After we got the song stuck in our brains, we used it to find the median  of our data. Then we used it to find the mean of our data. The mean is the same as the average.

We will do the mode and range on a different day.
