The below formula is used to calculate the Z score:

Z = (x- µ) / σ

Where the supplied arguments are as below:

Z = It denotes the Z score value.
X = The value to be standardized.
µ = Mean of the given data fix values.
σ = Standard deviation of the given data ready values.

Then a drop-down list of functions will open. Click on Statistical functions from the listing. It volition open a listing of functions. Click on STANDARDIZE function from the list equally per the beneath screenshot.

Then it will open up a Role Arguments dialog box. Enter the Cell value B4 under field X.

Enter the Hateful value in the second field, Hateful, which is mentioned under Cell B15.

Enter the Standard Deviation value in the third field, Standard_dev, which is mentioned under Cell B16. Click on OK.

The result will exist equally given below.

Drag this formula for the balance values, and it will pop upwards the Z score values in excel as shown beneath:

Caption

If we clarify the information, the highest Z score value is 2.082778, which is the Z score value of Nick Brown, who has achieved the highest score in the exam.
The smallest Z score value is -0.98521, which is the lowest Z score value of Adrian Steve, who has accomplished the lowest score in the examination.

Students who have achieved scores more than than the mean value get positive Z scores.
Students who have achieved scores less than the mean value become negative Z scores.
If the Z score is zero, that means the student's score is the same as the mean value.

Excel Z Score – Case #ii

We have given the below data values.

To calculate the Z score or standard score, nosotros need to decide the first hateful and standard deviation in excel.

Allow's apply the Boilerplate formula for calculating the mean of the given dataset.

It will requite you the Average or Mean value.

For calculating standard deviation, let's apply the STDEVPA function for the given data values as per the beneath screenshot.

It will give you the standard deviation value.

At present we volition calculate Z score values in excel. For this, employ the STANDARDIZE function for the given information values as per the below screenshot.

The result will be equally given below.

Drag this formula for the residuum values. The Final event is given below:

As we tin can see, the positive value of Z scores are college than the mean value, and the negative value of Z scores are lower than the mean value.

Things to Recall

The Z score tells u.s.a. a number of standard deviations that are away from the mean of the distribution or dataset.
The data values which are higher than the mean Z score volition be a positive value.
Data values which are below the mean Z score will be a negative value.
The z score value is probably used for statistical analysis.
