Question
a study examined the effects of different exercise programs on the health of captive dogs. Dogs randomly assigned to different exercise programs within each of these age groups. Their health was then monitored 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 not used in this study.
Statement 3
A control group was not used in this study.
Solution
Based on the information provided:
Statement 1: FALSE. The text does not provide any information about blinding being used in the study. Blinding is a practice where the subjects (in this case, the dogs) or those administering the exercise programs do not know which program is being given to prevent bias. There is no mention of this in the text.
Statement 2: FALSE. The text mentions that dogs were randomly assigned to different exercise programs within each age group. This is a form of blocking, where subjects are grouped based on certain characteristics (in this case, age) before being randomly assigned to different treatments.
Statement 3: TRUE. The text does not mention a control group, which would be a group of dogs not undergoing any exercise program for comparison. Without this information, we can assume that a control group was not used in this study.
