Deviance is also known as the error in a statistical model. Suppose the mean height (standard deviation) jumped by a group high jumpers was 1.89(0.05) m. One of the individuals jumped 1.95 m. Calculate the deviance score.
A) +0.06
B) -0.06
C) +0.6
D) -0.6.

The deviance score is calculated by subtracting the observed value from the expected value and dividing by the standard deviation. In this case, the expected value is the mean height of the high jumpers, which is 1.89 m.

Deviance score = (observed value - expected value) / standard deviation
Deviance score = (1.95 - 1.89) / 0.05
Deviance score = 0.06

Since the observed value is higher than the expected value, the deviance score is positive. Therefore, the correct answer is A) +0.06.
