Variables
This is the variable that is manipulated in order to measure its effect on the dependent variable.
What is the independent variable (IV)?
A testable prediction of the relationship between two or more variables.
What is a hypothesis?
These are standards that guide individuals to identify good, desirable or acceptable conduct.
What is ethics/ethical standards?
This type of data is information that was not collected directly by the current researcher.
What is secondary data?
It is a subset or part of the population
What is a sample?
This variable cannot be separated from that of the IV and has an effect on the DV.
What is a confounding variable?
This group is not exposed to the independent variable (IV).
What is a control group?
This ethical concept involves consideration of the extent to which living things have an intrinsic value.
What is respect?
This displays data in columns and rows.
What is a table?
This sample does not adequately represent the key characteristics of its population.
What is a biased sample?
This is the dependent variable (IV) for a study how sleep affects the reaction speed of participants.
What is reaction speed?
This experimental design often requires a larger number of participants to ensure the spread of participant variables within the sample will match the distribution of the population.
What is between subjects design?
This is done at the end of the experiment to ensure that participants leave understanding the experimental aim, results, and conclusion.
What is debriefing?
This type of graph is often used to enable comparisons of different categories of data.
What is a bar chart?
It is the process of selecting a sample from a population comprised of various subgroups in such a way that each subgroup is represented.
What is stratified sampling?
This effect/variable is controlled by using counterbalancing.
What is the order effect/situational variable?
An example of this experimental design is researchers testing the cognitive function of participants before and after using TikTok.
What is within subjects design?
A professor has stated that students will fail the subject if they do not participate in their study is a breach of this ethical guideline.
What is voluntary participation?
These are measures of central tendencies.
What is mean, median, and mode?
This procedure is used to place participants in groups/conditions so that they are likely to be in one group as the other.
What is random allocation?
What is the double blind procedure?
A researcher is using this experimental design to test the effect of sleep deprivation on memory. Each participant is randomly allocated to either sleep or no sleep. Each participant completes a memory test before and after.
What is mixed design?
A researcher has chosen to not publish their findings due to results being unfavourable for them is a breah of this ethical concept.
What is integrity?
An example of this data is the researcher asking participants to rate their happiness when exercising on a scale of 1-5.
What is primary, quantitative, subjective data?
This law suggests that as sample size increases, the sample more closely reflects the attributes of the population.
What is the law of large numbers?
