QUESTION ANSWER

1 Express a quarter as a percentage.

2 Convert 0.65 to a fraction.

3 What was the lowest common denominator to use for question 2?

4 In a study, 13 participants are women and 26 are men. Express the proportion of women to men as a part-to-part ratio (suitably reduced).

5 In the study above, what fraction of the total participants are men?

6 In a study to investigate the capacity of short-term memory, six participants remembered 7 words, three remembered 6 words and one remembered 9. What is the mean number of words remembered?

7 Jon recorded the ratio of black to white mice in his study as 6:2. Reduce this ratio.

Express the following as you would in a psychological report:

8 The probability of results being due to chance is equal to 5%

9 The probability that the results occurred by chance is equal to or less than 5%

10 If p = 0.05, what is the probability that results are not due to chance? (Express your answer as a percentage.)

Round off the following numbers to 2 decimal places

11 6.459

12 10.009

13 3.8755

14 Jim’s scores showed a negatively skewed distribution. Was the mode higher or lower than the mean?

15 Draw the symbol for ‘proportional to’

16. Write out ‘six is less than twelve’ using numbers and mathematical symbols

17 What is the range of the following numbers?

10, 12, 12, 14, 16, 27, 28, 36, 39, 41, 45, 49, 52

18 If the standard deviation of a set of results is small, does it mean there is a small or large range of scores?

19 In a survey, Jimmy asked a group of participants to classify themselves as being from one of 5 regions of the country. What measure of central tendency would he use for this information?

20 A health psychologist collects data on the number of calories eaten by participants. She expresses these in blocks of 0–500; 501–1000, etc. What type of graph should she use?
