Question
In rejecting a null hypothesis ($H_0$), a researcher is likely to commit which type of error ?
The correct answer is
Type II error
Rejecting Null Hypothesis Error
In hypothesis testing, researchers make decisions about a null hypothesis ($H_0$). Two types of errors can potentially occur:
- Type I Error ($\alpha$): This error happens when a researcher rejects the null hypothesis ($H_0$) even though it is actually true.
- Type II Error ($\beta$): This error occurs when a researcher fails to reject the null hypothesis ($H_0$), but $H_0$ is actually false.
The question specifically asks about the error committed when a researcher decides to reject the null hypothesis ($H_0$).
Following the provided correct answer, rejecting the null hypothesis ($H_0$) is associated with committing a Type II error.

Important Questions from Hypothesis testing - Teaching
- Type II error occurs when :
- The null hypothesis in nonparametric test often _______.
1. Includes specification of a population's parameters
2. Is used to evaluate some general population aspect
3. Is very similar to that used in regression analysis
4. Simultaneously tests more than two population parameters - The _______ test determines whether there is a significant difference between the observed and hypothesized distribution for a sample.
1. Independence
2. Coefficient of determination
3. Correlation analysis
4. Goodness-of-fit - Match the LIST-I with LIST-II
LIST-I LIST-II A. One-Tailed Test I. Null hypothesis is rejected if the sample value is significantly higher or lower than the hypothesized value of the population parameter B. Paired difference Test II. A hypothesis test of the difference between the sample means of two independent samples C. Two-Tailed Test III. A sample value significantly above the hypothesized population value will lead to rejection of the null hypothesis D. Upper-Tailed Test IV. Concerned only with whether the observed value deviates from the hypothesized value in one direction
Choose the correct answer from the options given below: - The null hypothesis that all slope coefficients are simultaneously equal to zero is tested in logit model by:
