  1. Which scale of measurement has equal intervals and a true zero point?

    Answer: Ratio

    Ratio scales, such as number of counseling sessions attended, have equal intervals and an absolute zero.

  2. A researcher wants to compare mean depression scores across three different treatment groups. Which statistical test is most appropriate?

    Answer: One-way ANOVA

    A one-way ANOVA compares means across three or more independent groups on one factor.

  3. A researcher examines whether gender is related to preference for individual versus group counseling, using frequency counts. Which test fits best?

    Answer: Chi-square test of independence

    Chi-square tests whether two categorical (nominal) variables are associated using frequency data.

  4. A Type I error occurs when a researcher:

    Answer: Rejects a true null hypothesis

    A Type I error is a false positive, rejecting a null hypothesis that is actually true, with probability equal to alpha.

  5. According to Cohen's conventions, an effect size (d) of 0.80 is considered:

    Answer: Large

    Cohen labeled d values of 0.2, 0.5, and 0.8 as small, medium, and large, respectively.

  6. In a positively skewed distribution, which ordering of central tendency measures is typical?

    Answer: Mean > median > mode

    In a positive skew, the tail extends to the right and pulls the mean above the median and mode.

  7. Increasing sample size while holding other factors constant generally does what to statistical power?

    Answer: Increases it

    Larger samples reduce standard error, making true effects easier to detect and increasing power.
