The probability of rejecting the null hypothesis given that it is true describes the:
What does aÂ Â Z-score of 2.5 indicate?
The observation is 2.5 standard deviations above the mean.
The p-value is closer to 0 than 1
The test results do not conform to a normal distribution.
The alpha level is 0.025
How is the actual effect size in a population usually determined?
It must be estimated based on the best literature available.
Multiply the projected effect size by the standard deviation in the control group
Divide the difference between the mean in the experimental group and the mean in the control group by the standard deviation of the experimental group
It is estimated based on the anticipated effect size relative to power.
What is the purpose of hypothesis testing?
It determines whether a hypothesis is true
It helps the researcher to develop a null hypothesis
It helps rule out an alternative hypothesis
It determines whether a hypothesis is clinically significant
You know the following is true when conducting a hypothesis test
You should determine your significance level or alpha before conducting your statistical test.
Your significance level is higher when your p value is higher.
Your decision is an error if the p value is greater than alpha
When you conduct your statistical analysis, you should adjust your significance level to ensure you achieve statistical significance.
