Question

please help me with this: Suppose a teacher gives 10 points for putting your name on a 100 point test. The minimum score on that test is 10 and the maximum score is 100. Write an absolute value equation that represents the minimum and maximum scores. Use x to represent the scores.

Answer 1

Suppose there are n observations in a data set consisting of the observations x1, x2, x3, ..., xn.

Rounding rule: round to one more decimal place than the highest number of decimal places contained in the data.

The formula can also be represented as sigma * xi / n.

x bar = SAMPLE MEAN

Mu = POPULATION MEAN

n= sample size
N= POPULATION SIZE

The sum of the deviations from the mean is always equal to 0.

The mean will always be pulled towards any outliers.

Ex: the average price of similar televisions at different stores. This is quantitative data that does not have outliers since the TVs at the different stores are similar
