Thursday HW

Today in class we took all of our chapter 7 notes; tomorrow we'll do some practice multiple choice, and then Monday it's on to chapter 8! We'll have a chapter 7 vocab quiz and math quiz next week! (Tuesday). I have posted the slides for the end of today's notes at the bottom of this post since we had to rush! If you missed them get these into your notes!

Tonight please describe the two associations provided in class (on the half-sheet) or below. See the bottom of this post for the weekend homework if you're feeling ambitious. 

• Remember, when describing scatterplots you should comment on the shape, direction, strength, and reference r (if you have it); then, write a "Based on this scatterplot, as _______ increases, ______ increases/decreases statement. And always be sure everything is in context!

• Look at question c on the answer key for last night's homework to see a sample!

• Or, try to use this writing template for describing an association:
• The association between __(explantory)____ and ___(response)___ is ___(shape)___, ___(direction)____, and __(strength)__ with a correlation of __r__ . Based on the scatterplot, as ______(describe the association shown in context)____.

• For example, consider yesterday's class context...
• The correlation between the age a child first spoke and Gesell score is roughly linear, moderately strong, and negative with r = -0.774. Based on the scatterplot, the earlier a child speaks his/her first words, the higher their predicted Gesell score. (Or, as the age a child first speaks increases, the predicted Gesell score decreases).

• Here are tonight's homework problems in case you lost yours....

And if you're feeling ambitious, here's our weekend homework--this will be the only book homework from chapter 7 and will be checked on Monday!

And here are the last 4 slides of our notes--we rushed through this, so if you missed anything here you go! You'll want this info for tomorrow's classwork.
