Which of these curves is normally distributed?
Which of the following sets of data is approximately normally distributed?
Consider the following normal distribution.
In a normal distribution:
use the number of deviations from the mean (standard scores) to describe deviations from the mean in normally distributed data sets
calculate quantiles for normally distributed data with known mean and standard deviation in practical situations
use the 68%, 95%, 99.7% rule for data one, two and three standard deviations from the mean in practical situations
