Answer 1: Quasi-Experimental Method Answer 2: the independent variable is made up of predefined groups Answer 3: Quality of sleep Answer 4: High-quality sleep and low-quality sleep Answer 5: Cognitive Performance Answer 6: Ordinal Dr. Smith is interested in understanding the impact of sleep quality on cognitive performance. In her study, she recruits 60 college students and divides them into two groups based on their self-reported sleep quality: those who report high-quality sleep and those who report low-quality sleep. Over the course of two weeks, each group completes a series of cognitive tests utilizing Likert scale items designed to measure their memory and problem- solving abilities. Dr. Smith wants to determine if there is a difference in cognitive performance between the two groups. Study Design: This is a [Select] [Select] because Independent Variable (IV): [Select] Levels of the Independent Variable (IV): High-quality sleep and low-quality sleep Dependent Variable (DV): [Select] using the Ordinal Scale which is measured

Question
In one image it shows the answers I picked for each box. it says I got some of them wrong but I’m not sure which. I will list down the answer choice options for each box. Study design: -Correlational Method -True Experimental method -quasi-experimental method Because: -of the use of random assignment -the independent variable is made up of predefined groups -we are assessing a relationship without any manipulation Independent variable - quality of sleep - problem solving abilities - cognitive performance - memory test scores Dependent variable - student recruitment method - cognitive performance l - quality of sleep - type of cognitive tests Please help me figure out what I got wrong. Thank you!
