What Not is
Not is a logical operator used to negate a statement or condition. It is typically used in mathematics and computer programming.
The steps of using Not are as follows:
Step 1: Identify the statement or condition that needs to be negated.
Step 2: Determine if the statement or condition is true or false.
Step 3: Place the word “not” before the statement or condition.
Step 4: Evaluate the statement or condition with the negation in place.
Step 5: Record the result of the evaluation.
Examples
- Rejecting the null hypothesis in a statistical test.
- Estimating a confidence interval which does not include the hypothesized value.
- Excluding an outlier from a data set.
- Finding that an observed difference is not statistically significant.
- Determining that a correlation coefficient is too small to be meaningful.
- Calculating a probability value that is less than the significance level.
- Calculating a p-value that is greater than the alpha level.
- Finding that a linear regression model does not fit the data well.
- Rejecting the assumption of normality in a data set.
- Finding that a population variance is not equal to a hypothesized value.
