Trend Analysis
What are two measures of central tendency?

_______ _____ is determined by adding all values then dividing by the number of values. Is known as the “average”.
Arithmetic Mean
_____ _____ is appropriate for describing central tendency of data that is normally distributed. Best at describing data trends with values clustered together.
Geometric Mean
_____ _____ is a measure of how “spread out” or “closely grouped” data is.
Standard Deviation
How do you calculate the standard deviation of a data set?
Suppose you have four quiz scores: 1, 3, 5, and 7. The mean is 16 ÷ 4 = 4 points. Subtracting the mean from each number, you get (1 – 4) = –3, (3 – 4) = –1, (5 – 4) = +1, and (7 – 4) = +3. Squaring each of these results, you get 9, 1, 1, and 9. Adding these up, the sum is 20. In this example, n = 4, and therefore n – 1 = 3, so you divide 20 by 3 to get 6.67, which is the variance. The units here are “points squared,” which obviously makes no sense. Finally, you take the square root of 6.67, to get 2.58. The standard deviation for these four quiz scores is 2.58 points.
How many sample are required to perform trend analysis?
