Compared to others, which one of the following is not robust to outliers? a) Mean b) Median c) Mode d) 50th percentile

tatyana61 [14]

Answer:

The mean.

Step-by-step explanation:

The mean is not robust.

The presence of an outlier greatly affects the value of a mean.

An example will illustrate this.

Find the mean of the numbers 2 3 5 6 34.

34 is an outlier. The mean = (2+3+5+6+34) / 5 = 10.

Now if we replace the outlier with a number closer to the others:

Say we have 2 3 5 6 8 :

The mean = (2+3+5+6+8) / 5 = 4.8 which is a much truer measure of centrality than 10.

The bearing of point Y from point X is 070°.

Shkiper50 [21]

The bearing of point X <u>from</u> point Z is 285°

<h3>Calculating bearings </h3>

From the question, we are to determine the bearing of point X from point Z.

Consider the diagram attached

The bearing of point X <u>from</u> point Z is the measure of the angle from the North of Z in the <u>clockwise direction</u> to the line that goes to X.

That is,

The bearing of point X from point Z = 270° + 15°

The bearing of point X from point Z = 285°

Hence, the bearing of point X from point Z is 285°
