Question 1

In a study comparing two teaching methods, researchers assign students to Group A or Group B based on their ID numbers being even or odd. If the variance of test scores in Group A is $\sigma_A^2 = 25$ and in Group B is $\sigma_B^2 = 36$, and the sample sizes are $n_A = 100$ and $n_B = 100$, calculate the standard error of the difference between means $SE = \sqrt{\frac{\sigma_A^2}{n_A} + \frac{\sigma_B^2}{n_B}}$.

A researcher uses a within-subject design to test a new drug. If the effect of the first treatment persists and influences the outcome of the second treatment, what is the specific term for this confounding phenomenon?

Accepted Answer

carryover effect

Question 3

In a factorial RCT with two factors (Drug dose: Low vs High) and (Diet: Standard vs Keto), if there are $k_1 = 2$ levels for dose and $k_2 = 2$ levels for diet, how many unique treatment groups are required for a full factorial design?

Question 4

In a crossover trial, each participant acts as their own control, which mathematically reduces the variance of the treatment effect estimate compared to a parallel group design assuming the correlation between measurements is $\rho > 0$.

Accepted Answer

True

Answer

False

Question 5

A researcher conducts a case-control study to determine the odds ratio (OR) for a disease given an exposure. If the number of exposed cases is 40, unexposed cases is 10, exposed controls is 20, and unexposed controls is 30, calculate the OR using $OR = \frac{a/c}{b/d}$.

Answer

Measuring the effect of a controlled laboratory temperature on chemical reaction rates

Question 7

In a cohort study, if the incidence rate of disease in the exposed group is $I_e = 0.05$ and the incidence rate in the unexposed group is $I_u = 0.01$, calculate the Relative Risk (RR).

Question 14

If a researcher is analyzing a dataset where the number of emergent concepts $C$ grows according to the function $C(t) = 5\ln(t+1)$, where $t$ is the number of hours spent in field observation, determine the number of emergent concepts after $t = 99$ hours.

Accepted Answer

Question 17

In a meta-analysis, if the weighted effect size is calculated as $\bar{x} = \frac{\sum w_i x_i}{\sum w_i}$, where $w_i$ represents the inverse variance of study $i$, the meta-analysis is effectively minimizing the total variance of the combined estimate.

Answer

False

Question 18

Rewrite the following biased sentence to be objective and formal: 'The study was clearly a complete disaster because the researchers failed to account for basic variables.'

Accepted Answer

The study's findings may be limited by the omission of key control variables.
