Research Methods Part 1

A teacher wanted to know there was a gender difference in the time spent doing homework between students at his school. The teacher got a random sample of 20 girls and 20 boys and got them to record the time they spent doing homework at the end of each day for 4 weeks. What type of experiment is this? (a)  

• Field experiment
• Quasi experiment
• Independent measures
• Repeated measures

A teacher wanted to know there was a gender difference in the time spent doing homework between students at his school. The teacher got a random sample of 20 girls and 20 boys and got them to record the time they spent doing homework at the end of each day for 4 weeks. One limitation of this type of experiment?

• Can't establish cause and effect because of extraneous variables

• Highly controlled experiment, lacks ecological validity.

• The materials used could be influenced by social desirability bias

• The sample used were unrepresentative of the school

Random Sampling: Reorder the following

• Write every students name in the school on individual bits of paper

• Put the names into a hat

• Pull out 40 names

• Ask these students to participate in your experiment

• Pull out more participants if someone does not want to participate

A teacher wanted to know there was a gender difference in the time spent doing homework between students at his school. The teacher got a random sample of 20 girls and 20 boys and got them to record the time they spent doing homework at the end of each day for 4 weeks. Why does he need a pilot study?

• The teacher wants to see if his hypothesis is correct

• To test the behavioural categories are clear

• To check that the questionnaire used is clear

The teacher got a random sample of 20 girls and 20 boys and got them to record the time they spent doing homework at the end of each day for 4 weeks. Which question is the best example for a closed question?

• Why is homework important?

• Do you mind doing homework - yes or no?

• On a scale of 1-10 how much do you like doing homework?

Where is the mean?

Is this a positive or negative skew...

• Positive skew

• Negative skew

A thematic analysis...

• analyses qualitative data and changes it into quantitative data

• analyses qualitative data and keeps it qualitative

• use sampling methods

• uses an unstructured observation

What is this defining: 'the strength of the relationship between two variables in a population'

• effect size

• correlation co-efficients

• intervening variables

• cost-benefit analyses

What type of consent is this discussing: 'asking a group of people who are similar to the participants, whether they would agree to take part'?

• Presumptive consent

• Prior general consent

• Retrospective consent
