The key terms would be not-equal/different  and  greater than / less than . For example, if you observed 10 students taking a statistics test the two following statements would be an example of a 1-sided hypothesis test and 2-sided test.

1. 1-sided: If 7 out of 10 students in a special tutorial class passed a statistics test, what is the probability that the extra tutorial pass rate is greater than the average pass rate which is 50%.
2. 2-sided:  If 7 out of 10 students in a special tutorial class passed a statistics test, what is the probability that the scores from the extra tutorial class are different than the average class pass rate of 50%.
