The range of given observations refers to the difference between the highest and lowest values in a set of data.

• Range is calculated by subtracting the lowest value from the highest value in the data set.

• For example, in a set of numbers {2, 5, 8, 10}, the range would be 10 - 2 = 8.

p value is a statistical measure that helps determine the significance of results in hypothesis testing.

• A p value of less than 0.05 is typically considered statistically significant.

• It is used to determine whether to reject the null hypothesis in hypothesis testing.

• The smaller the p value, t...read more

• Multicollinearity can lead to issues in the interpretation of regression coefficients, as it becomes difficult to determine the individual impact of each predictor variable on the outcome.

• It can inflate the standard errors of the coefficients, making them unstable and unreliable.

• Multicollinear...read more
