MANCOVA | Binomial test for a single proportion |
|
---|---|---|
Independent variables | Independent variable | |
One or more categorical with independent groups, and one or more quantitative control variables of interval or ratio level (covariates) | None | |
Dependent variables | Dependent variable | |
Two or more quantitative of interval or ratio level | One categorical with 2 independent groups | |
THIS TABLE IS YET TO BE COMPLETED | Null hypothesis | |
- | H0: $\pi = \pi_0$
Here $\pi$ is the population proportion of 'successes', and $\pi_0$ is the population proportion of successes according to the null hypothesis. | |
n.a. | Alternative hypothesis | |
- | H1 two sided: $\pi \neq \pi_0$ H1 right sided: $\pi > \pi_0$ H1 left sided: $\pi < \pi_0$ | |
n.a. | Assumptions | |
- |
| |
n.a. | Test statistic | |
- | $X$ = number of successes in the sample | |
n.a. | Sampling distribution of $X$ if H0 were true | |
- | Binomial($n$, $P$) distribution.
Here $n = N$ (total sample size), and $P = \pi_0$ (population proportion according to the null hypothesis). | |
n.a. | Significant? | |
- | Two sided:
| |
n.a. | Example context | |
- | Is the proportion of smokers amongst office workers different from $\pi_0 = 0.2$? | |
