Which of the following is qualitative data

• The number of digits recalled in a memory test

• The ages of a group of children taking part in a cross-sectional study

• The number of aggressive behaviours recorded after children watch a violent video

• Scores on an intelligence test out of 100

• Comments and feedback from children describing their experiences of a new teaching method

What purpose do clearly stated aims serve?

• Aims state clearly what the research intends to contribute and details how the research will be done.

• Aims state clearly in detail how research will be done and justify why research is being carried out.

• Aims state clearly how the research will be done and what conclusions are expected.

• Aims state clearly what the research intends to contribute and justifies the research being carried out.

• Aims predict a cause and effect relationship between 2 variables

Individuals who are sleep deprived will differ significantly in their reaction time, to those individuals who are not sleep deprived". If this is the experimental hypothesis, which of the below statements would be the correct null hypothesis?

• Greater sleep deprivation leads to a decrease in reaction time.

• Individuals who are sleep deprived will not differ in their reaction time from those individuals who are not sleep deprived.

• Individuals who are not sleep deprived will differ in their reaction time from those individuals who are sleep deprived.

• Individuals who have more sleep will differ in their reaction time from those individuals who are sleep deprived.

• The slower the reaction time the more sleep deprived the individuals are

If findings from research are replicated consistently they are considered to be what?

• Valid

• Reliable

• Ethnocentric

• Correct

• True

When the same procedures are used in giving a test to all people, the test has been

• validated

• normalised

• operationalised

• standardised

• compromised

Which of the following is the best way to test a hypothesis according to the hypothetical-deductive method by Popper?

• By rejecting the hypothesis

• By repeating a study looking for consistency in outcomes

• By finding evidence which supports the null hypothesis

• By finding evidence which supports the hypothesis.

• By looking for instances where the hypothesis fails

A student plans to investigate the effects of practice on IQ test performance. Some participants are given two practice tests prior to the IQ test, whereas other participants do no test beforehand. What is the dependent variable in this study?

• Independent

• Dependent

• Control

• Random

• Stimulus

Which one of the following is an advantage of an independent measures design?

• They are very in-depth

• Researcher do not need to gather as many participants

A group of primary schools conducted an experiment to find out if reading books to 7 year olds for 10 minutes during the school day would increase IQ. In four of the schools, teachers read a book to their students each day. In the other four schools there was no reading. What was the independent variable?

• The age of the children.

• The type of book being read to the children.

• Whether or not the children had a book read to them.

• Whether the children had a book read to them for 5 minutes or 10 minutes each day.

• The IQ scores of the children at the end of the experiment.
