The data value x = 45 has a deviation value of 12. Explain the meaning of this.

The data value x = 84 has a deviation value of -20. Explain the meaning of this.

The deviation value of a data value indicates how much that value deviates or differs from a reference point, which is often the mean or average value.

In the case of x = 45 with a deviation value of 12, it means that this particular data value is 12 units greater than the reference point.

On the other hand, in the case of x = 84 with a deviation value of -20, it means that this data value is 20 units less than the reference point.

In general, a positive deviation value indicates that the data value is above the reference point, while a negative deviation value indicates that the data value is below the reference point. The magnitude of the deviation value represents the distance or difference between the specific data value and the reference point.
