Test whether two sample proportions from independent samples come from populations with the same population proportion. |
3. |
Test whether two sample proportions from matched samples come from populations with the same population proportion. |
4. |
Test whether the population proportions for two multinomial categories are equal. |
Averages
|
1. |
Test whether a sample mean is statistically consistent with a theoretical value of the population mean. |
2. |
Test whether two sample means from independent samples come from populations with the same population mean. |
3. |
Test whether two sample means from matched samples come from populations with the same population mean. |
