1. When population parameters are unknown, a t test should be conducted instead. 2. They were defined differently, had different population parameters , and different concepts of prognosis. 3. Data are also lacking regarding the population parameters and ecology of individual plant species. 4. However, a statistic, when used to estimate a population parameter , is called an estimator. 5. After any particular sample is taken, the population parameter is either in the interval, or not. 6. Population parameters are estimated with many point estimators.7. It requires knowing the population parameters , not the statistics of a sample drawn from the population of interest. 8. *This template produces the map automatically if the Map parameter isn't defined, and also applies the template to the Population parameter . 9. Confidence intervals consist of a range of values ( interval ) that act as good estimates of the unknown population parameter . 10. Unlike the " t "-test statistic, the effect size aims to estimate a population parameter and is not affected by the sample size.
