Qualitative quantitative Experimental methods

What is the main difference between quantitative and qualitative research?

• Quantitative research focuses on subjective experiences, while qualitative research focuses on objective data.

• Quantitative research collects numerical data, while qualitative research collects non-numerical data.

• Quantitative research uses interviews, while qualitative research uses statistical methods.

• Quantitative research aims to produce rich descriptions, while qualitative research aims to test hypotheses.

What is the advantage of using an independent measures design in an experiment?

• It reduces participant variables.

• It controls for extraneous variables.

• It eliminates demand characteristics.

• It avoids order effects.

What are demand characteristics in an experiment?

• The variable the experimenter manipulates.

• The clues in an experiment lead the participants to think they know what the researcher is looking for.

• The ways that the experimenter can accidentally influence the participant through their appearance or behavior.

• The degree to which an investigation represents real-life experiences.

What is the dependent variable in an experiment?

• The variable the experimenter manipulates.

• The outcome of a study. This is what you measure at the end.

• All variables which are not independent variables but could affect the results of the experiment.

• Variable(s) that have affected the results apart from the independent variable.

What is the purpose of random allocation in an experiment?

• To limit the effects of participant variables.

• All of the above.

• To avoid bias in how the experiment is carried out.

• To ensure that all participants have an equal chance of taking part in each condition.

What is the disadvantage of using a repeated measures design in an experiment?

• There may be order effects.

• It may lead to demand characteristics.

• It reduces participant variables.

• It avoids order effects.

What are extraneous variables in an experiment?

• The ways that the experimenter can accidentally influence the participant through their appearance or behavior.

• The variable the experimenter manipulates.

• All variables which are not independent variables but could affect the results of the experiment.

• The clues in an experiment lead the participants to think they know what the researcher is looking for.

What is the aim of qualitative research?

• To produce objective, empirical data.

• To identify patterns and make predictions.

• To test hypotheses and make measurements.

• To explore subjective experiences and uncover new insights.

What is the aim of quantitative research?

• To produce rich and detailed descriptions.

• To avoid order effects and control for extraneous variables.

• To explore subjective experiences and uncover new insights.

• To collect numerical data and analyze it using statistical methods.

What is the matched pairs design in an experiment?

• An experimental design where the experimenter manipulates the variable.

• An experimental design where pairs of participants are matched in terms of key variables.

• An experimental design where different participants are used in each condition of the independent variable.

• An experimental design where the same participants participate in each independent variable condition.
