Description
Two identical footballs, one air-filled and one helium-filled, were used
outdoors on a windless day at The Ohio State University's athletic complex.
Each football was kicked 39 times and the two footballs were alternated with
each kick. The experimenter recorded the distance traveled by each ball.
Format
A data frame with 39 observations on the following 3 variables.
Trial trial number
Air distance
traveled by air-filled football (yards)
Helium distance
traveled by helium-filled football (yards)
