resear methods 3
| Question | Answer |
|---|---|
| Independent variable | variable being manipulated, purpose:determine if causes or influences changes in the dv |
| dependent variable | variable being measured/observed, purpose: show the outcome or effect of the iv |
| control variable | variable that a researcher keeps constant during study purpose: to isolate the effect of the iv & enure that any changes in the DV are due to the IV only |
| covariance 3 causal criteria to a study | two variables are related, if one changes the other changes two, do the results show the causal variable , is related t th outcome variable |
| Temporal precedence 3 causal criteria to a study | cause must come before the effect in time, does the study design ensure that that the casual variable come before the outcome variable |
| internal validity 3 causal criteria to a study | must ensure there is no alternative explanation, or outside factors that caused. the change, does the study design rule out alternative explanations for the results |
| cofounding variables | potential alternative explanation for a research finding a threat to internal validity, hidden third factor that could be responsible for the observes relationship between 2 variables |
| manipulation check | extra dv that confirms that your IV worked, that participants actually experienced intended change/condition, Did they test if participants noticed/reacted to manipulation?Did they confirm that the IV caused the intended psychological or physical change? |
| within | all subjects under one variable |
| between | samples split into different groups w/ each having a set variable manipulated |
| - fiixed factors - p value Jamovi | -IVS - less than .05= statistically significant |
| main effects | F=(df,df)= F,P= F=(df, residual,)F, P= |
| direct replication 3 types of replication | study in which researchers repeat the og study as closely as possible to see if the same results can be found again |
| conceptual replication 3 types of replication | researchers examine the same research question but use different methods to see if the underlying theory is the same across different situations |
| replication-plus-extension 3 types of replication | researchers replicate og study but add variables or conditions to test additional questions |
| counterbalance types of counterbalance | repeated measures experiment,presenting subject the levels of IVS in sequence to control order effects, changes in subjects caused by or not condistions |
| full counterbalancing types of counterbalance | all possible condition order use |
| partial counter balancing types of counterbalance | some but not all of the possible conditions orders are present |
| latin square types of counterbalance | system of partial countr balancing to ensure that every condition in a within groups design appears in each position at least once |
