Hence, it’s sometimes called the 68 95 and 99.7 rule. The first part of the rule states: 68% of the data values in a normal, bell-shaped, distribution will lie within 1 standard deviation (within 1 sigma) of the mean. Next, the second part of the rule states:

WebFeb 5, 2024 · By the 68-95-99.7 rule we would expect about 68% of 100, or 68 students to score between 60 and 80 on the test. Two times the standard deviation is 20. If we subtract and add 20 to the mean we have 50 and 90. We would expect about 95% of 100, or 95 students to score between 50 and 90 on the test.
