Researchers randomly assign 80 volunteers to a new study method or a comparison method. Why does random assignment strengthen a causal comparison of the methods? A. It guarantees identical groups before treatment.B. It makes volunteers a random sample of all students.C. It tends to balance potential confounders between groups.D. It guarantees a statistically significant difference.Check answer Question 9 · Unit 1: Exploring One-Variable Data and Collecting Data · standard
A college wants to estimate the mean one-way commute time, in minutes, for all students enrolled this term using a random sample. Commute times vary among students. Which investigative question best matches this purpose? A. How many minutes did one named student take to commute yesterday?B. What range of plausible values estimates the population mean one-way commute time in minutes for all students enrolled at this college this term?C. How many minutes are there in an hour?D. How many students are enrolled at every college in the country?Check answer Question 10 · Unit 1: Exploring One-Variable Data and Collecting Data · challenge
Before collecting data, a researcher plans to randomly sample seedlings of one species from a nursery's current stock, then randomly assign them to fertilizer or no fertilizer under otherwise matched conditions. The stated purpose is to test whether fertilizer increases the population mean 14-day height gain, measured in centimeters, for that nursery stock. Which investigative question matches this purpose? A. Does fertilizer decrease the population mean 14-day height gain for this nursery stock?B. What fraction of all trees worldwide has green leaves?C. Does fertilizer cause a greater population mean 14-day height gain in centimeters for this nursery stock than no fertilizer?D. What is the arithmetic mean height gain in the collected sample, without drawing a conclusion about the nursery stock?Check answer All Advanced Placement subjects
