Ready meal

Many things can influence people's eating habits and how much food we consume, including the appearance of food and how it is served. For example, some research suggests that people put less food on a red plate, and eat less from it, than a white plate. To investigate this further, psychologists want to use the experimental method to study the effect of plate colour on food consumption.

21 Write a one-tailed alternative hypothesis for this study.

22* Explain how you would conduct a study using the experimental method to investigate if there is a difference in how much food people eat off a red plate compared to a white plate. Justify your decisions as part of your explanation. You must refer to:

• the sampling technique to obtain participants for the study

• how you would operationalise your independent variable

• how you would operationalise the dependent variable to obtain quantitative data

• details of how one ethical consideration would be addressed.

You should use your own experience of practical activities to inform your response.

Outline one strength of using a repeated measures design in this study.

Outline one weakness of using a repeated measures design in this study.

Outline one way you could obtain qualitative data in this study.

Evaluate the use of qualitative data in this study.

Evaluate the external validity of this study.

Explain how the data has been ranked in this study.

Explain why the data for the rating of extroversion for participants (b) and (l) have both been given rank 6.5.

Draw a fully labelled scatter diagram showing the data collected in this study.

Outline two conclusions from this scatter diagram.

Calculate the mean rating of extroversion. Show your workings and present your finding to 2 significant figures.

Explain why it is more appropriate to use the mean, rather than the median, to calculate central tendency in this study.

Calculate the correlation coefficient for the data collected in this study using the formula for Spearman’s ranked correlation coefficient presented below. Show your workings.

Write the significance statement for the analysis performed on this data using Spearman’s ranked correlation coefficient.

Outline one weakness of not having qualitative data in this study.

Outline two things that could have affected the validity of the data collected in this study.
