8A1 Data
Lesson 2: Pie Charts Reading
Prequisites
Fractions of 360
Proportion
Measuring Angles
Key Skills
Proportion of Total
Measuring Angles
Key and Title
Comparison
Probability
WE sheet for finding total, was a complete disaster, too procedural not enough understanding especially for a top set. Perhaps the entire thing would have been better taught as a 1 degree = how many people?
Lesson 3: Range and Quartiles
Prequisites
Differences
Key Skills
Range
Maximum
Minimum
Upper Quartile
3(n+1)/4
Lower Quartile
(n+1)/4
Emphasise reordering even more
Lesson 5: Frequency Tables
Prerequisites
3Ms
Key Skills
Tallying
Mean
Value x Frequency
Median
(n+1)/2
Plotting
Bar Chart
Bar Line
Tables are difficult to interpret, practice forming a frequency table first. Then link median in table to median of list more explicitly, maybe establish n+1 rule earlier in the unit.
