Unit 5 Data: What does it all MEAN?

This week we will begin our data and statistics unit in seventh grade math.  The essential questions that we will answer through our studies include the following:

How can predictions and decisions be made about a large population?
What is a measure of variation?
How is the shape of the data use to analyze data?

We will begin with the third question this week as we look closely at the results of the Unit 5 Post-test.

The follow illustration shows our achievement compared to all seventh-graders in the district.

Standard / Cluster	Hoyt Middle School 53 Students	District Average
MA.7.7.G.6 (7) Curriculum Resources (41)	62.64%	44.74%
MA.7.7.G.1 Curriculum Resources (16)	53.21%	50.97%
Questions	64.2%	53.8%
Overall Exam	64.2%	53.8%
MA.7.7.G.4 (7) Curriculum Resources (12)	64.72%	59.18%
MA.7.7.G.5 (7) Curriculum Resources (9)	76.23%	60.31%

What do YOU notice?

While our mean (or average) score on the test was only 64.2% correct (we would like to see 75%), our mean score was ABOVE the mean score for the district (53.8%).  What this means is that we've worked hard, but we still have lots of work ahead.
