Answer :
Final answer:
The effect size for the 10-week squat training program is calculated using the formula for Cohen's d, which is 1.0 in this case. This indicates a strong effect of the program on the athlete's ability. The correct option is b. 1.0.
Explanation:
In this problem, we are asked to calculate the effect size which is a statistical concept used to measure the strength of the relationship between two variables. In this context, we are examining the effect of a 10-week squat training program on athletes. The formula for calculating effect size (Cohen's d) is the difference between two means divided by the standard deviation.
The two means are the pretesting 1RM squat mean and the posttraining 1RM squat mean, and the standard deviation is provided. Using the numbers provided, our calculation would be (156 - 150) / 6 = 1. Therefore, the effect size for the 10-week squat training program is 1.0, which corresponds to option b. This suggests that the program had a strong effect on the athlete's squatting mean. Hence, b is the correct option.
