Z score Calculator
Top
The value of z-score says, how many standard deviations an observation is from the mean. A z-score can be calculated from the following formula.
$Z$ = $\frac{x - \mu}{\sigma}$
Where,

$x$ = Standardized Population Mean

$\mu$ = Population Mean

$\sigma$ = Population Standard Deviation.
Z score Calculator is a statistics tool that calculates z-score from the given population mean and standard deviation. We just have to enter the value of x, value of $\mu$ and value of $\sigma$. This calculator really makes the work easier and faster without any confusions.

  1. Find the z score for the following values: x = 35, $\mu$ = 35 and $\sigma$ = 11.180


    Step 1 :  

    The given values are x = 35, $\mu$ = 35 and $\sigma$ = 11.180



    Step 2 :  

    Using Z score formula, we have


    Z score = $\frac{x - \mu}{\sigma}$


               = $\frac{35 - 35}{11.18}$



    Step 3 :  

    or Z = 0



    Answer  :  

    Z score is 0.



  2. Find the z score for the following values: x = 5, $\mu$ = 4.5 and $\sigma$ = 1.118


    Step 1 :  

    The given values are: x = 5, $\mu$ = 4.5 and $\sigma$ = 1.118



    Step 2 :  

    Using Z score formula, we have


    Z score = $\frac{x - \mu}{\sigma}$


               = $\frac{5 - 4.5}{1.118}$



    Step 3 :  

    Z =0.4472



    Answer  :  

    Answer: Z score is 0.4472
