Probability Summary GCSE New syllabus up to grade C
Just the basic facts on two sides of A4. No problems and just a basic example of each fact. Its really a summary to guide revision and problem solving and to help with the vocabulary found in textbooks.

Mean and median of wage data
If you make people redundant and those who remain take a pay cut, it is possible for the mean wage to rise. The median gives a clearer picture of the changes.

Eval: students got the point very quickly (a touch of the paulo freires). The feeling was that it would have been better to have different wages rather than the same figure each time, so I'll modify this handout. That modification would also increase the usefulness as a revision aid for mean and median. The percentage change calculation caused some searching in notes as well.

Module 1 probability practice questions for GCSE
Two sides A4 with a summary of the basic formulas/ideas in a table (probability formula, expected frequency formula, probabilities add to one formula).

Four questions: complete the table on a spinner with expected frequency, balls in a bag, fraction line question (find events that will have a probability of a given fraction), and a two way frequency table question.

The fraction line question went down very well tonight,

Data: box and whisker plot summary and question
Just a quick summary of the box and whisker plot and a question with the min, lq, median, uq and max given and a scaled grid to draw the chart.

Meant as a quick 10 minute revision task and a summary for revision by the students nearer the Module 1 exam.

Data: scatter diagram question
Another one side 10 minute question to check recall of the vocabulary, spotting the outliers and drawing line of best fit. Data set about age and blood pressure after exercise. One data point has been fiddled so it is clearly an outlier. Asks for how removing this point would change the correlation. Line of best fit and a prediction question.

Data: Cumulative Frequency Diagram question
One side A4 with a frequency table, a spare column for the cumulative frequencies and a grid with scales to plot the curve on. Questions ask for median, quartiles and iqr. Also a question about what percentage more than a certain value of the variable.

Meant for a quick 10 minute revision exercise for Module 1 exam soon, and so the students have (another) one side summary of cumulative frequency.

Data: frequency diagram question
Just for revision for the module 1 exams soon. A frequency diagram question with grid and data set all on one side of A4.

I quickly sketch the answers on the interactive whiteboard using 'overlay', then we make some revision notes based on what each student finds they need to remember.

Probability basics
Two side worksheet with the definition of an event, and an outcome and some questions based on coins, dice and packs of cards.

The first activity was designed to get people talking. A much better talking point was the National Lottery!

Representing Data
Stem and Leaf Diagrams section here is 'good enough' to get the idea across. I'll provide a couple of data sets for students to build one with, and to get used to the need to have two passes through the data to put the leaves into size order...
