Answer:
0 (Zero)
Step-by-step explanation:
Mary has jogged each day for the past nine days. The data of her jogging is:
6, 7, 5, 0, 6, 12, 8, 6, 9
Now, we need to figure out the outlier.
We need to define what is an outlier:
"Outliers" are those values that "lie outside" the other values. Here in the given data set, it lies at an abnormal distance from other values in a random sample. We can see that all the values are ranging in a particular interval except 0.
0 in the given data set is lying outside of the other values. Therefore, 0, is the outlier in the given data set.
