Study Notes
Hypothesis Testing
- Significance level represents the maximum probability of rejecting a true null hypothesis, typically set to 0.05 or 0.01.
- A 1% significance level is represented by a value of 0.01.
p-Value and Significance Level
- If the p-value is greater than the significance level, the null hypothesis is accepted, indicating the observed result is likely due to chance.
- If the p-value is lower than the significance level, the null hypothesis is rejected, indicating a statistically significant result.
Critical Value and Rejection Region
- A critical value represents the value of the test statistic that separates the rejection region from the acceptance region.
- The critical value is compared to the test statistic to decide whether to reject the null hypothesis.
- The rejection region is the area of the distribution where the null hypothesis is rejected.
Null and Alternative Hypotheses
- The null hypothesis typically assumes no significant relationship between variables.
- The alternative hypothesis is the hypothesis being tested against the null hypothesis.
- The alternative hypothesis is used to describe the expected relationship between variables.
Acceptance Region
- The acceptance region is the area of the distribution where the null hypothesis is accepted.
- The acceptance region falls on the opposite side of the critical value.
Other Concepts
- Correlation analysis is an appropriate statistical tool for examining relationships between variables.
- The purpose of determining the significance level is to establish a threshold for determining statistical significance.
- Critical values are used to separate the rejection and acceptance regions, guiding the decision to reject or accept the null hypothesis.
