One Sample Poisson Rate Test¶
From Excel click...
QXL Stat Tools Tab > Hypothesis Tests > Attribute Tests > One Sample Poisson Rate
| Test type: | Compare one rate to reference |
|---|---|
| Data: | Attribute -- Counts |
| Number of Variables: | 1 |
| Number of Groups: | 1 |
| Assumptions: | One sample of count data, Total Occurrences > 10 |
The One Sample Poisson Rate Test is a hypothesis test used for testing rate equality between a population and a reference. It assumes one sample of count data with 10 or more total observations.
Hypothesis tested:
| H0 : | Rate1 = Reference |
|---|---|
| H1 : | Rate1 ≠ Reference |
where Rate1 is the population's rate.
Step #1: Select data source for One Sample Poisson Rate Test.¶
Data for the One Sample Poisson Rate Test can come from an Excel spreadsheet, SQL data source, or it can be entered manually.
Step #2: Options.¶
Standard options
-
'Not equal to' option. Select this option to run a two-tailed test. The null hypothesis is that the rates are equal.
-
'Less Than' option. Select this option to run a lower-tailed test. The alternative hypothesis is that the rate of the first dataset is smaller than the rate of the second dataset.
-
'Greater Than' option. Select this option to run an upper-tailed test. The alternative hypothesis is that the rate of the first dataset is greater than the rate of the second dataset.
-
'Hypothesized Rate': Enter a reference rate.
Example¶
-
Run Quantum XL > Hypothesis Tests > Attribute Tests > One Sample Poisson Rate.
-
In the Options dialog, select 'Not equal to' test and enter the hypothesized rate.
Update¶
The One Sample Poisson Rate Test is updatable. After you create the analysis, you can change its data source or add new data to the data source and simply update the analysis.
