Using correlation coefficient, means, and standard deviations to find the equation of a line provides a straightforward method for understanding the relationship between two variables …

The most common way to calculate the correlation coefficient (r) is by using technology, but using the formula can help us understand how r measures the direction and strength of the linear …

What are z-scores? A z-score measures exactly how many standard deviations above or below the mean a data point is.

To test that null hypothesis, Miriam takes a sample, sample size is equal to seven. From that, she would calculate her sample mean and her sample standard deviation, and from that, she …

His sample mean was four years and his sample standard deviation was two years. Rory wants to use these sample data to conduct a t test on the mean. Assume that all conditions for …
