Sample questions from Data Recording, Analysis and Presentation
Answer each one closed book first, then open the answer.
-
Raw data tables, standard form and decimal form
Why is a summary table presented separately from the raw data table?
Show the answer
The raw data table shows every original score, whereas the summary table condenses those scores into descriptive statistics such as the mean and standard deviation. -
Significant figures, estimation and the range
The highest score in a data set is 47 and the lowest is 12. State the range.
Show the answer
The range is 35. -
Quantitative, qualitative, primary and secondary data
Give one strength of qualitative data.
Show the answer
It provides depth and detail about meaning and experience that numbers cannot capture. -
Measures of central tendency
What is the mean, and how is it calculated?
Show the answer
It is the arithmetic average, found by adding all the scores together and dividing by the number of scores. -
Percentages, fractions, ratios and graphs
When is a line graph the appropriate form of display?
Show the answer
When showing how a variable changes continuously, for example across successive trials or over time. -
Normal and skewed distributions and probability
What is a negatively skewed distribution?
Show the answer
A distribution in which most scores are high and a long tail of low scores stretches out to the left. -
Parametric criteria and choosing a non-parametric test
State the criteria for using the Chi-square test.
Show the answer
It is used to test for a difference or an association where the data are nominal frequencies and the sets of data are independent. -
Degrees of freedom, choosing a test and mathematical symbols
Distinguish between the symbols < and <<.
Show the answer
The symbol < means less than, whereas << means very much less than.
The 15 subtopics
One subtopic is one session. Work down the list.
| Subtopic | What it covers | Questions |
|---|---|---|
| Raw data tables, standard form and decimal form | Recall questions on raw data and what a raw data table contains, separating summary tables, stating units in column headings, and converting values between standard form and decimal form. | 8 |
| Significant figures, estimation and the range | Recall questions on rounding to significant figures and decimal places, counting significant figures, reporting results sensibly, estimation, finding the range, estimating a mean from a total, and keeping raw data after a study. | 13 |
| Nominal, ordinal and interval data | Recall questions on nominal, ordinal and interval data with examples, why rating scales give ordinal data, which level carries most information, and which measure of central tendency suits each level. | 11 |
| Quantitative, qualitative, primary and secondary data | Recall questions on quantitative and qualitative data with a strength of each, converting qualitative data into numbers, primary and secondary data, and identifying the type of data used in example studies. | 11 |
| Measures of central tendency | Recall questions on measures of central tendency, finding and evaluating the mode, median and mean, calculating a median and a mean, and choosing the measure that best represents a data set with an outlier. | 11 |
| Measures of dispersion | Recall questions on measures of dispersion, calculating and evaluating the range, the variance and standard deviation, and what large and small standard deviations show about a set of scores. | 10 |
| Percentages, fractions, ratios and graphs | Recall questions on expressing results as percentages, fractions and ratios, frequency tables, choosing line graphs, pie charts, bar charts, histograms and scatter diagrams, and calculating a pie chart angle. | 12 |
| Normal and skewed distributions and probability | Recall questions on the purpose of inferential tests, the normal distribution, positively and negatively skewed distributions and where the mean, median and mode lie, and probability in research findings. | 8 |
| Significance levels, Type 1 and Type 2 errors and critical values | Recall questions on significance levels and the usual 5% level, when to use 0.01, Type 1 and Type 2 errors and how the significance level affects each, and how tables of critical values are used. | 10 |
| Parametric criteria and choosing a non-parametric test | Recall questions on the criteria for parametric tests, the criteria for the Mann-Whitney U, Wilcoxon, Chi-square, Binomial Sign and Spearman's rho tests, choosing a test for example studies, and comparing observed and critical values. | 13 |
| Degrees of freedom, choosing a test and mathematical symbols | Recall questions on degrees of freedom for Chi-square, the three questions for choosing an inferential test, and the mathematical symbols ∝, ~, < and << used to report relationships and significance. | 8 |
| Representativeness, generalisability and types of reliability | Recall questions on representativeness and generalisability, internal and external reliability, inter-rater, test-retest and split-half reliability, and ways to improve the reliability of observations and questionnaires. | 11 |
| Types of validity | Recall questions on validity and its types, including internal, face, construct, concurrent, criterion, external, population and ecological validity. | 9 |
| Demand characteristics, social desirability and researcher bias | Recall questions on low ecological validity in artificial memory tasks, demand characteristics and how participants respond to them, social desirability, researcher or observer bias and effects, and controlling researcher bias. | 8 |
| The BPS Code of Ethics and ethical issues in research | Recall questions on the BPS Code of Ethics principles of respect, competence, responsibility and integrity, informed consent, the right to withdraw, confidentiality, protection of participants, debriefing, deception, and ethical issues in a staged field study. | 12 |
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.
