Day 119: Appropriate Measures of Center and Variability / Constant Speed / Scatter Plots

Today in Math 6, students in 1 and 3° received their Graphical Representation quiz from Friday. Mr. Giomini displayed the results using a box-and-whisker plot and posed questions to students regarding information that could and could not be found looking at the graphical representation. 

Students then worked in pairs to complete a task where they had to determine the most appropriate measures of center and variability to describe a given data set based on the context in which the data values were collected.  

In 2°, Math 6 students continued to work with unit rates.  With Lesson 10.5: Constant Speed, students built upon knowledge from previous units to explore another type of rate.  Today they learned that speed is a rate comparing units of distance to units of time.  Mr. Giomini attempted to blend problems like the ones they will solve in science classes using the formula d = rt (distance = rate x time).  

During 7 °, students in Math 6+ received their Graphical Representation Quiz from Friday.  Some of the common mistakes were: not providing a title for the histogram, not labeling the x-and y-axis for the histogram, and incorrectly determining quartile 1 and 3 for the box-and-whisker plot which then made calculating the interquartile range incorrect.

Once mistakes were polished up and discussed, Mr. Giomini introduced scatter plots which have been worked with briefly in the past two weeks.  Today's focus was on determining a line of best fit as well as understanding the difference between the population and sample size.
