Homework Wed 10/10

Today we finished the lesson on measures of variability. In class we did the pg. 65, OYO question, finding means and mean absolute deviations for the data, then comparing sets of data. We looked at using concept maps for an organizational/conceptual tool for the unit and will be creating them using the handout by the end of Unit 1.
For homework finish the checkpoint on pg. 67. We transformed a data set, Jenny's clock times from pg. 65, OYO, by adding 12 and multiplying by 2 to see how the mean and mean absolute deviations changed. Prepare for the next assessment on measures of variability on Friday. Understand:
Mean, Median, Mode.
Range, Interquartile Range (IQR), and Mean Absolute Deviation (MAD).
The five-number summary of data:
minimum, lower quartile or quartile 1 (Q1), median, upper quartile or quartile 3 (Q3), and maximum.
Percentiles and quartiles.
Create a box and whisker plot or modified box and whisker plot to compare data sets.
