Score: 2.5 of 5 points Consider the following statements: (1) Additional variables that can influence the outcome of a study/experiment are called lurking variables. To ensure that these unforeseen influences are removed, a researcher can use random assignment to fill the control and treatment groups. (2) To eliminate "the power of suggestion", a researcher can perform a blind or double-blind study/experiment. Select any statements that are true. A Statement 1 B Statement 2

Statement 1 is a true gem of wisdom! Lurking variables can sneak up on researchers like ninjas in the night, affecting results in sneaky ways. By using random assignment, researchers can assign participants randomly to control and treatment groups, helping to mitigate the impact of those pesky lurking variables and ensuring a fair fight between the two. And let’s talk about statement 2 – it’s also spot-on! The power of suggestion can be as powerful as the latest blockbuster movie, impacting participants' responses. To tackle this, researchers can implement blind or double-blind studies where the participants and/or researchers don't know who is in which group, thus keeping those expectations from swaying the results. Now that's what I call a double olive on the cocktail of scientific integrity!
