BATs describe the different types of experimental

and non-experimental techniques in Psychological research.

evaluate the strengths and weaknesses of each type of technique

Identify ethical issues and how to deal with them

Identify and use descriptive stats

10-15 mins


Activity 2

In groups choose 2 types of research from….

lab experiment, natural experiment, field experiment, correlation, case study, questionnaire, interview, observation, content analysis.

For each jot down .. A definition 2 examples and why used in these examples- strengths/ weaknesses

We will share responses in

Attachments and Memory topics Highlight the ethical issues in each Say how they were or could have been

dealt with 15-20 mins

Levels of measurement

Nominal: named categories (count how many in each)

Ordinal: points in order on a scale (gaps between points not equal)

Interval and Ratio: points in order with equal gaps (ratio has a real zero)

think … NOIR

Which levels of measurement are being used in each of the

following tests?


Levels of measurement

Decisions about data

What do you need to decide about displaying data?

• What aspects of the data are interesting?• How can these be summarised?• How can these summaries be tabulated?• How can these summaries be illustrated?

Presenting numerical data

Summary data tables:• tables should include totals or a measure of

central tendency (mean, median or mode)• where appropriate, tables should include a

measure of spread (eg range or standard deviation)

• Remember that the choice of measures of central tendency and spread depend on the level of measurement


Measures of central tendency and spread

Measure of central tendency:• Mode: for nominal data• Median: for ordinal data• Mean: for interval or ratio data

Measure of spread:• Range: for ordinal data• Standard deviation: for interval or ratio data


Illustrating data: graphs and charts

• Bar charts• Histograms• Line graphs• Scatterplots


Bar charts

• used to present totals and averages

• bars must be separated in space

• title & axis labels


Histograms

• used to present scores, totals and averages

• bars must be adjacent

• title & axis labels


Line graphs


Scatterplots
