Study Time – Fun with Statistics

This week’s Woot dives into the fascinating, and sometimes scary, world of statistics. The activity itself is pretty straightforward. Use it as either as a warm-up or review for high school statistics. You could also use it as a review for middle school students. As you’ll see, the activity demonstrates how to use equivalence in Woot Math in fun and rewarding ways.

Task #1

The activity starts with a tap-an-image problem. Students tap the outlier in the data.

– Task 1: Tap the Outlier –

This is a good refresher if your students are familiar with the concept of an outlier. If they aren’t, it is a good opportunity for instruction. I recommend lingering a little on the context here. Discussing what the data means primes a discussion about hard work and a growth mindset. Although the data is not real, it helps students understand what an outlier could be in a real world context.

Task #2

Task 2 is a review of different types of correlation. We thought it was a weak correlation. Since there is only one outlier, some students may argue that it is strong correlation. After your students submit a response, you can have a discussion by de-selecting the “Reveal Answer” option. Then you can view and discuss the results of the class without revealing the right answer. You can also press the “Assign Groups” button to automatically create groups for small-group discussion.

Task #3 and #4

Tasks 3 and 4 both provide an equation of a line representing best fit, and students are asked to determine a test score given study time. They also highlight an interesting feature of the short answer task type. While designing a task, you can set it to accept equivalent forms of the correct answer. Click on the gear icon to set the various equivalence options.

– Edit Equivalence Options –

For this task we turned off operations because an answer of 0.1*3+0.5 doesn’t seem like they have quite figured it out yet. If operations were on, the tool would accept 0.1*3+0.5 as a correct answer. We left fractions on because converting 0.8 to a fraction is helpful extra practice. There’s nothing wrong with that.

– Task #3: Accepted Answers –

In the answer blank you can also separate multiple correct answers with a semicolon. As long as the number comes first, the software will give you access to the equivalence tools. If you do a letter or word first, it will treat the answer as a string and let you change the number of typos allowed. The way we have the answer box setup, it will accept responses of 0.8, 80%, B- or any fractional equivalent to 0.8. This way your students will not get it wrong if they think outside the box, interpreting a grade of 0.8 as a B-.
