Parker is testing 2 different types of ant killer in his yard. he purchases brand a and brand b from the home improvement store. he applies brand a in the front yard on monday and brand b in the backyard on saturday. he then compares the ant hills on sunday and determines that brand a is more effective than brand b. why is his conclusion not valid?

Given scenario is :

Parker applies Brand A in the front yard on Monday and Brand B in the backyard on Saturday.

He compares the ant hills on Sunday and determines that Brand A is more effective than Brand B.

This is not a valid conclusion because brand A had been spread out for 6 days from Monday to Sunday and brand B had been applied for only 1 day.

It is obvious that brand A will have been more effective as it worked for 6 days unlike brand B.

For a valid conclusion, Parker should apply the pesticides on the same day and check the results on the same day.

depends on how many days you are talking about
