If a study involves exactly three conditions, which of the following is a basic method for conducting simple random assignment?
A researcher is assigning 90 participants to three experimental conditions by using a computer to generate a random integer from 1 to 3 for each individual. True or False: This method of simple random assignment guarantees that the study will finish with an exactly equal number of participants (30) in each condition.
A researcher is evaluating different strategies to assign participants to three distinct experimental conditions. Rank the following procedures from the least methodologically sound to the most methodologically sound based on how effectively they achieve an equal and independent probability of assignment for every participant.
You are developing a standard operating procedure (SOP) for a new research study that involves five distinct experimental conditions. To ensure a valid simple random assignment using a computer-based random integer generator, arrange the following steps in the correct sequence to create a functional and unbiased protocol for each incoming participant.
When a researcher uses a coin flip for a two-condition study, or a computer to generate random integers between and for a three-condition study, what is the underlying methodological purpose of these simple random assignment procedures?
A psychology researcher is planning a study and needs to select a simple random assignment method. Match each study scenario with the correct randomization technique based on the number of conditions involved.
A researcher is investigating the effect of three different types of study environments (Quiet, Lo-fi Music, and Television) on memory recall. To assign each of the 60 participants to one of these conditions with equal probability, the researcher uses a computer to generate a random integer for each person. To properly represent all three conditions, the researcher should generate a random integer from 1 to _____.
In psychology research, a basic physical method for conducting simple random assignment in a study with two conditions is flipping a _____ for each participant to determine their group assignment.
A researcher who uses a coin flip (heads = Condition A, tails = Condition B) to assign each participant to one of two conditions is applying the same core principle as a researcher who uses a computer to generate a random integer from 1 to 3 to assign each participant to one of three conditions: in both cases, every individual participant has an equal probability of being assigned to any available condition. True or False?
