Did you complete the exam practice questions on last week’s handout? Is your revision material for research methods up-to-date? You will have a SHORT in-class test on experimental research methods in the week commencing: 26th November

Dedicated Improvement and Reflection Time Add your target grade Summarise WWW and EBI on your feedback sheet. Make 1-3 improvements to your work (e.g. re-write parts, answer questions, make corrections, etc.)

Starter: Let’s play taboo! Pick a card and roll the dice. You must communicate the key concept on the card without using the three related terms underneath. 1 point for a correct guess; lose a point if you use one of the words on the card. Describe it Act it Model it Draw it Choose how to taboo Mime it

Graphs and charts are descriptive statistics too!

The Normal Distribution Use your knowledge of the properties of normal distributions to answer question 1 on page 3. Finished? Have a go at question 2. Mean Median Mode

c) 50 (the same as the mean). a. Percentage of UK population with scores between 100 and 115 = 68 /2 = 34% Question 2 136 (68% of 200 = 68/100 × 200) b) 32 (16% of 200 = 16/100 × 200) c) 50 (the same as the mean). b. 95% of population fall between 100 – 30 (2 SDs) = 70 and 100 + 30 (2 SDs) = 130 c. Approx. percentage of population with scores above 115 = (99.7/2 = 49.85) – (68/2 = 34) = 15.85 = 16% Mean IQ = 100 1 SD = 15

Skewed Distributions Negative Skew Scores at the higher end of the data. The curve has a tail on the left. Mode > Median > Mean E.g. scores on a very easy test Positive Skew Scores cluster at the lower end of the data. The curve has a tail on the right. Mode < Median < Mean E.g. scores on a very difficult test

Apply Your Knowledge – page 7 Identify which type of graphical display should be created, justifying your decisions. Create the appropriate graphical displays. Interpret the results of the graphical displays to draw conclusions. Finished? Complete the exam practice questions on descriptive statistics and distributions (page 7-8)

Plenary: Post a Question In pairs/small groups, write down ONE question based on ONE of the learning objectives for today’s session. This will be ‘sent’ to another class
