  1. Functional Question (and lesson) Foundation (Statistics 2) For the week beginning ….

  2. Lesson Plan – Finding the Mean, Median and Mode

  3. Assessment Objective - AO3 Developing AO3 skills is a process that depends on giving learners confidence to: · Try different approaches · Make mistakes and rectify them in a constructive environment · Justify decisions and explain consequences · Express ideas and communicate conclusions in a variety of ways and to different audiences. AO3 seeks to assess a learner’s ability to: · Process information · Pose problems and pursue them · Conjecture and investigate within mathematics · Reason concisely · Evaluate and check methods and results · Present solution(s) effectively There is a link to the three strands in Functional Mathematics: · Represent (strategy) · Analyse · Interpret However, not all AO3 questions will be “functional”.

  4. L0 To calculate the mode, mean, median and range of a set of data.. RAG Mean, Median, Mode, Range, Frequency 7-Nov-14 Mode - The most commonly occurring value (number). Median – Arrange the values (numbers) in order from smallest to biggest and find the value (number) in the middle Mean – Add up all the values (numbers) and ÷ by the number of values (numbers.) Range – Subtract the smallest value (number) from the largest value (number.)

  5. Mode - The most commonly occurring value (number). Median – Arrange the values (numbers) in order from smallest to biggest and find the value (number) in the middle Mean – Add up all the values (numbers) and ÷ by the number of values (numbers.) Range – Subtract the smallest value (number) from the largest value (number.) Mode - The most commonly occurring value (number). Median – Arrange the values (numbers) in order from smallest to biggest and find the value (number) in the middle Mean – Add up all the values (numbers) and ÷ by the number of values (numbers.) Range – Subtract the smallest value (number) from the largest value (number.)

  6. Mode - The most commonly occurring value (number). Median – Arrange the values (numbers) in order from smallest to biggest and find the value (number) in the middle Mean – Add up all the values (numbers) and ÷ by the number of values (numbers.) Range – Subtract the smallest value (number) from the largest value (number.) Mode - The most commonly occurring value (number). Median – Arrange the values (numbers) in order from smallest to biggest and find the value (number) in the middle Mean – Add up all the values (numbers) and ÷ by the number of values (numbers.) Range – Subtract the smallest value (number) from the largest value (number.)

  7. Starter Activity Ms Hindle rolled a dice 11 times and recorded her scores in the table below. Record the scores in the frequency table and present the raw scores as a bar chart. Raw Scores

  9. How can we find the mean, median, mode and range of our raw scores? Raw Scores

  10. We’re going to roll the dice another 11 times and record our results in a frequency table. How can we find the mean, median, mode and range from the frequency table?

  11. We’re going to roll the die another 11 times and this time we will record our results in a bar chart. How can we find the mean, median, mode and range from our bar chart?

  12. Today’s Task Match each bar graph to the correct statistics table.

  13. Mini - Plenary What strategies did you use to match the cards? How did you produce the missing graph to match the data?

  14. AO3 question (Foundation) These are the weekly wages, in pounds, paid to 11 workers. 275 160 842 275 420 359 315 275 740 280 195 James says the average wage is £280. Jane says the average wage is £376. Show how they can both be correct.
