Question
a study examined the effects of different diests on the behaviour of captive monkeys. Monkeys were assigned to different diets and their behaviour was observed. the researchers observing the behaviour were not aware which monkey had received which dieta. Use the information about the study to decide if each of the following three statements are TRUE or FALSE.
Statement 1
Blinding was used in this study.
Statement 2
Blocking was used in this study.
Statement 3
A control group was not used in this study.
Solution
Statement 1
TRUE - Blinding was used in this study. This is indicated by the fact that the researchers observing the behavior were not aware of which monkey had received which diet.
Statement 2
FALSE - There is no information provided in the text that suggests blocking was used in this study. Blocking is a technique used in experimental design to reduce the effects of confounding variables. There is no mention of any such technique being used in this study.
Statement 3
TRUE - The text does not mention a control group being used in this study. A control group would be a group of monkeys that were not given any special diet, to compare the effects of the different diets. Since there is no mention of such a group, we can assume that a control group was not used.
