Qualitative Variables – Variables that are not measurement variables. Their values do not result from measuring or counting.
How do you find intervals in research?
Since they have decided to use a 95 percent confidence interval, the researchers determine that Z = 1.960….Step #5: Find the Z value for the selected confidence interval.
| Confidence Interval | Z |
|---|---|
| 90% | 1.645 |
| 95% | 1.960 |
| 99% | 2.576 |
| 99.5% | 2.807 |

What is the class interval of 10 20?
Thus, class limits of 10 – 20 class intervals in the exclusive form are 10 and 20. In inclusive form, class limits are obtained by subtracting 0.5 from lower limitand adding 0.5 to the upper limit. Thus, class limits of 10 – 20 class interval in the inclusive form are 9.5 – 20.5.
