What does a p-value of 0.03 mean in hypothesis testing?
Answer: There is a 3% probability of obtaining results this extreme if the null hypothesis is true
A p-value of 0.03 means there is a 3% chance of observing data as extreme as the results if the null hypothesis were true.
Which research design is best suited to establish a cause-and-effect relationship?
Answer: True experimental design with random assignment
True experiments with random assignment allow researchers to control variables and infer causation from observed differences.
What does a standard deviation of zero indicate about a data set?
Answer: All values in the data set are identical
A standard deviation of zero means there is no variability at all, so every score in the data set is exactly the same value.
In APA style, which statistical test would be used to compare the means of three or more independent groups?
Answer: One-way ANOVA
A one-way ANOVA compares means across three or more independent groups to determine if at least one group differs significantly.
What is the main advantage of using a double-blind procedure in an experiment?
Answer: It reduces both participant and experimenter bias
Double-blind procedures prevent both participants and researchers from knowing group assignments, reducing demand characteristics and experimenter expectancy effects.
A positively skewed distribution has which characteristic?
Answer: A long tail extending to the right with most scores clustered on the left
In a positively skewed distribution, the tail extends toward higher values on the right while the majority of scores are concentrated at the lower end.
