Unit 2 Assessment Prep

...... is when a variable is defined by the researcher and a way of measuring that variable is developed for the research

Which is the correct definition of RESEARCHER BIAS

• When the experiment is not reflecting real life

• When the researcher make sure nothing is influencing the experiment

• Where the outcome of an experiment is affected by the researcher.

• Where the researcher uses self report measures to identify issues in the study

Identify a variable from Milgram's Behavioral study of obedience

Which sampling method was used in the Milgram study?

• Random Sampling

• Systematic Sampling

• Self Selected Sampling

• Snowball Sampling

Which is an advantage of self selected sampling?

• Give access to a variety of participants (eg: all the same people who read a particular newspaper), which may make the sample more representative and less bias

• Unbiased, all the members of a target population have an equal chance of selection

• Unbiased as participants are selected using an objective system

• Likely to be more representative than other methods.

Which is a disadvantage of the self-selected sampling method

• Need to have a list of all members of the target population and then contact all of those selected which may take some time

• The sample is not likely to be a good cross section from the population as its friends of friends

• Sample is biased in other ways because participants are likely to be more highly motivated to be helpful or have extra time on their hands. This results in volunteer bias.

Which methodology was used in the Kohlberg Study?

• Experiment

• Observation

• Cross-sectional study

• Longitudinal Study

What is ecological validity?

• a measure of how test performance predicts behaviours in real-world settings.

• a measure of how researchers control the experiment

Which of the following is an issue with the research method for Kohlberg?

• Biased sample

• Too many participants

• No IV or DV

If a participant wants to impress the researcher this might result in.....
