Question

Krusty was told that a certain itching powder was the newest best thing on the market; it even claims to cause 50 % longer lasting itches. Interested in this product, he buys the itching powder and compares it to his usual produce. One test subject (A) is sprinkled with the original itching powder, and another test subject (B) is sprinkled with the Experimental itching power. Subject A reported having itches for 30 minutes, Subject B reported to have itches for 10 hours.

Answer 1

Hi, you've asked an incomplete question. The full question reads;

1. Identify the:

• Control Group
• Independent Variable
• Dependent Variable

2. Explain whether the data supports the advertisement's claims about its product.

Answer:

• Subject A
• The "certain itch powder"
• The time of itchiness  

Explanation:

1. Remember, the Control group in research often refers to the group in a research experiment that who are not subjected to any treatment, rather they are used as a comparison scale to see how other tested subjects perform.

• We also need to note here that the independent variable here refers to a variable or factor that does not change (ie it is independent), but which results in changes in other variables. From the study, the "certain itch powder."

• "The time of itchiness" is a dependent variable because it does change, or can be affected by the independent variable.

2. Remember, the advertisement of the "certain itching" "claims to cause 50% longer lasting itches". Hence, we can conclude that the data support the advertisement claims since subject B did itch over 50% longer than subject A. In fact, we are subject B itched for 10 hours, not the 30 minutes subjet A itched.
