Dry Erase Workmat for Finding Five Number Summary, IQR, in addition to Outliers

My Algebra 1 students are inwards the midst of our next-to-last unit of measurement of the year: information analysis. This is my showtime twelvemonth of teaching Algebra 1 where my students do non conduct keep to conduct keep an end-of-instruction examination inwards Algebra 1. This way that I don't conduct keep to rush through concepts inwards club to conduct keep plenty fourth dimension to review for a essay inwards Apr fifty-fifty though schoolhouse doesn't exit until May. Usually, our unit of measurement on information analysis is super-short equally a result.

This year, I conduct keep plenty of fourth dimension to genuinely prepare my students' science at reading information displays together with creating their ain information displays. Today, I desire to portion an action I created to give my students do alongside finding the v number summary together with IQR of a laid upward of data. Students together with therefore used this information to cheque for together with position outliers.

I started past times creating a workmat template inwards Publisher. I purpose Publisher to do most all of the resources I postal service on my blog.

I titled it "Identifying Outliers Practice," but it also gave my students do alongside finding the v number summary together with IQR. Not certain what I could championship it to include those equally well...

I printed this workmat on 11 x 17 cardstock (affiliate link) that I slid into 1 of my 11 x 17 dry out erase pockets (affiliate link). I conduct keep a laid upward of smaller, 8.5 x xi dry out erase pockets (affiliate link), too. But, I prefer the 11 x 17 size (affiliate link) for partner work.

I also created a laid upward of information value cards (1-36) that jibe just into the information laid upward boxes on the operate mat.

Each laid upward was cutting apart together with placed inwards a tiny bucket from Dollar Tree.

These stacked upward real nicely betwixt classes!

Like many activities I create, I ended upward modifying the action throughout the 24-hour interval to improve it together with become far to a greater extent than effective. Originally, I had planned for each couple of students to curl a 12-sided move past times (from this set of polyhedra dice from EAI Education - affiliate link) to decide how many information values they should delineate from their bucket before starting.

My idea behind having them curl a move past times was that I wanted them to larn used to how to bargain alongside quartiles when in that location are an fifty-fifty number of values together with an strange number of values.

But, together with therefore my students were ending upward alongside information sets of 3, together with the information do only wasn't rigorous enough.

For my afternoon classes, I did away alongside the die together with had each couple of students delineate 12 information values from their buckets. This ended upward working soooo much better!

As students worked, I circulated the room together with checked for errors. In the motion-picture demonstrate above, the IQR should genuinely live 18.5.

As pairs finished, they would heighten their hands to conduct keep their calculations spot-checked.

One of the issues I didn't foresee alongside this action was that the bulk of students did non respect whatsoever outliers inwards their data.

It ended upward beingness okay because afterwards I cheque each pair's work, I would challenge them to do their ain information laid upward that had outliers.

This ended upward beingness the perfect extension activity!

I dear how much collaboration I tin terminate come across alongside my students inwards these pictures!

There are a few changes I would similar to brand inwards the time to come to this activity.

After students delineate their information values together with before they laid about doing whatsoever calculations, I would similar to conduct keep my students brand a prediction re: outliers.

Then, afterwards they complete all of their calculations, I would similar them to write a judgement explaining why or why non the information contains outliers. My students genuinely struggled alongside writing a judgement to justify their outliers on their quizzes. Need to start practicing that earlier!

Additionally, I would similar to do a laid upward of "challenge cards" for students to operate through. For example, each bill of fare would state them how many cards to select from the bucket. Students mightiness randomly choice cards, or they mightiness choice specific cards to effort together with orbit a specific thing.
