Question

Sora was given two data sets, one without an outlier and one with an outlier. Data without an outlier: 108, 113, 105, 118, 124, 121, 109 Data with an outlier: 108, 113, 105, 118, 124, 121, 109, 61 How is the mean affected by an outlier? The outlier did not affect the mean at all. The outlier made the mean higher than all the other values. The outlier made the mean lower than all the other values. The mean is centered around all the other numbers in both sets of data.
