Final answer:

Approximately 32% of data in a normal distribution is more than 1 standard deviation away from the mean.

Step-by-step explanation:

The percentage of data that is more than 1 standard deviation away from the mean in a normal distribution is approximately 32%.

According to the Empirical Rule, approximately 68% of the data is within one standard deviation of the mean, leaving approximately 32% outside this range.

For example, if the mean is 50 and the standard deviation is 10, values less than 40 or greater than 60 would be considered more than 1 standard deviation away from the mean.
