Hitung nilai yang dinormalisasi (skor-z)
=STANDARDIZE(x, mean, standard_dev)
| Parameter | Deskripsi |
|---|---|
x |
The value to normalize. |
mean |
The arithmetic mean of the distribution. |
standard_dev |
The standard deviation of the distribution. |
In the example shown, the formula in D5 is:
=STANDARDIZE(C5,$G$4,$G$5)
To calculate a z-score, you need to calculate the mean and standard deviation. The formulas in G4 and G5 are, respectively:
=AVERAGE(points)
=STDEV.P(points)
