A) What does a measure of variability indicate?Measure of variability indicates how widely the scores are spread or scattered around the central pointB) why do researchers use measures of variability when summarising their data?Researches use this as it provides researchers with information about how reliable any difference between two means is. 2. A) how is the mean calculated?By adding the scored together then dividing the total by the number or scores. B) What effect does extreme scored have on the data?Extreme scores have an effect on the data as they will increase the mean making it not 100% accurate.3. What specific information about variability of scores is provided by variance?The Variance represents the spread of scores around the mean. While calculation of the variance includes every individual score in a set of scores, the variance score which results provides a very general impression of the spread of those scores.4. A) what information does that standard deviation provide about the distribution of scores?The standard deviation summarises how far on average a scores differs from the mean in the same measure of units as the original data.B) What conclusions could be made about (A) and (B)?It can be concluded that (A) is differs more from the mean than (B).Learning Activity 8.27FeatureSelf-report methodsSurveyQuestionnaireInterviewRating scaleDescriptionIs a method of measuring attitudes that includes any technique requiring a participant to answer questionsIs a written set of questions designed to draw out information from people from a topic of interest.Usually involves questions that are asked by the researcher with the aim of obtaining information on a topic of research interest.

Learning Activity 9.251.

With reference to table 9.9 what conclusions can be drawn about: A) Age related.Judgements of risk taking behaviours are more common to exist in the 11-14 ages bracket for all types of risk taking behaviours when compared to the age bracket of 15-15 years. B) Sex differencesfemales are more likely to make judgments in all areas of risk taking behaviours than males.3. Suggest a possible correlationMales are more likely to commit the risk taking behaviours whereas on the other hand females are more likely to make judgment about them. Learning Activity 10.4 1.
