... Covariance = sxy = (1/ n-1) ∑ ( xi – x ) ( yi – y )= (1/ n-1) ∑ (= (1/7) * [(2 – 10) (15 – 5) + (2 – 12) (15 – 8) + ….+ (18-10) (15 – 10) + (10 – 9) (15 – 7)] = 19.286 (rounded). Since the covariance is positive, it indicates a positive relationship between x and y. b. Now if we want to get correlat ...

... A boxplot, is to describe several data features: center, spread, the extent and nature of any departure from symmetry, and “outliers”. The boxplot is based on the median and a measure of variability called the fourth spread, which are not sensitive to outliers. Order the n observations ascendingly a ...

... estimate of the population mean? Can you also see that the sample mean does not always equal the population mean? (That’s sampling error.) Here are a couple of other questions related to the sampling distribution of the mean. What proportion of the population scores fell at the mean ()? What propor ...
