    I personally think that OCR realised that they were being too soft on us with Statistics and haven't done any questions on standard deviation in a while so threw it all into one section.
    I feel so sorry for those who decided not to bother revising for standard deviation

    I think so but it was definitely wrong. The scenario was referring the the maths test scores of children who were stood up or sat down. There was nothing to do with words so it was definitely wrong
    Phew, I was sat there think where is the data for for 5 mins😂

    There was a bit about a study on people doing maths tests stood up or sat down, but one of the questions asked for mean % words recalled which wasnt even mentioned
    I think for this one you had to take the average score you calculated earlier, divide it by the maximum score of the test, then multiply it by a hundred to get the percentage.

    That 'your questionnaire' bullet point was a bit vague.
    Thats what I thought! I thought the last three bullet points in the 15 marker were all like interweaved

    It gave a (kind of incorrect) formula for standard deviation with the value 'n' under it and asked us to use the table about the young and old people's IQ levels to identify what N would be. I think the options were 6, 8, 12 and 35?

    Ohh ok. I put 6.

    In the SD calculation one, I originally put n-1 then I saw that formula again so I removed the -1 and only did n. Would that lose a mark?

    Can't quite remember it. If it it asked about the conditions separately then it would be 6. Did it ask about the old people group? Because if I remember correctly I put 6.

    I think N means number of participants and there were 6 in the condition, it's what I put anyway ^-^

    Guys, about the n-1/n thing in Standard Deviation.

    OCR have explicitly stated that either of those formulae are FINE- n-1 is the sample variance, n is the population variance.

    They have specified that either are correct for use in the exam and you will not be penalised for using one and not the other as both are technically correct.

    definitely higher than last year, there were few discriminating questions if that
