Hello blog readers,

This has been our final math unit. This unit included talking about mean, median, and mode, and correlation and causation. We learned how to find the average of data and the difference between correlation causation.

Mean, Median, Mode

To start off this unit we learned about mean, median, and mode. These are three kinds of ways we can find “averages”. Each of these are very simple to learn so I’m going to try and explain it. For the “mean” you add up all the numbers and then divide by the number of numbers you have. For “median” you try and find the middle, basically you just put your numbers in numerical order from smallest to largest and find the exact middle number. For “mode” you try and find the number or value that occurs most often. For example if you have 3 tens but only 2 of everything else the mode would be the 3 tens. If there is no number in the list that is repeated there is no mode for the list.

Correlation 

A correlation is a connection between two or more things that don’t cause each other. 

Causation

Causation is when one thing is the cause of something else.

After we learned all these things we got to know our project. For our project we had to come up with two questions like these.

Does _________ have a correlation with _________?

Does _______ cause ____________?

Mr. Gross gave us an outline of what he expected from us but he let us make our own critique sheets. I partnered with Jessie and started to think of questions we could do. It took us a day or two but we finally came up with two creative and very personalized questions. Then in class we all made posters showing our two questions and our plan.

Our questions were:

Does mangos consumed have a correlation with music listened to?

Does drinking mango juice cause insomnia?

In class we did a gallery walk and gave feedback to everyone.

This our poster and our feedback we got from our classmates.

After we got the basics for this project we got to work and we worked everyday to finish this project. First we started by making a evaluation critique rubric for ourselves. The next day we took a survey. Jessie and I went around and asked questions to lots of grade 9 kids. The questions we asked were “how many mangos do you eat a week?”and “how many hours of music do you listen to a week?” We took the surveys and we made a graph out of them. Then Jessie made a keynote while I calculated the mean, median, and mode.

Soon it was presentation time. Jessie and I did a good job presenting. We got almost everything in exceeding expectations, 3 in exceeding and 1 in meeting expectations. In the end I think this was a good final math project. I was able to keep my work level produced high even though its the end of the year. This has been scimathics in grade 9 goodbye.
