It also shows how to calculate the p-value from the z -table to find the probability of X in the normal distribution. It's an online statistics and probability tool requires an unstandardized raw value, mean of normal distribution, and the standard deviation.

The result will describe the measure of how many number of standard deviations between a value and the mean. Enter an unstandardized raw value, mean of normal distribution, and the standard deviation of the population in the box.

Press the GENERATE WORK button to make the computation. Input : Three real numbers as random member, mean and standard deviation of population or sample data; Output : A real number or a variable.

The Z -table helps to find the p-value of random variable in the normal distribution. In this case, the probability density function is of(x)=\frac1{\sort{2\pi}} ex{-\franc{x^2}{2}}$$ Because the standard normal distribution is used very often, there exist tables to help us calculate probabilities (Standard Normal Table).

By using the Z -Table we can find probabilities for a statistical sample with a standard normal distribution. This result represents UP(Z < z)$, as a left tail shows the probability that the random variable $ Z $ is less than the value of $ z $.

Using the Z -Table, find the row for $$1.1 and the column for $$0.03. Cumulative Standardized Normal Distribution. Using the z -table, find the row for $-$1.1 and the column for $$0.03. Cumulative Standardized Normal Distribution.

Note, the solutions will automatically be updated when either of the input date fields are modified or changed. Just enter your raw score, population mean and standard deviation, and hit “Calculate Z “.

Please enter your values above, and then hit the calculate button. If you're interested in using the z statistic for hypothesis testing, then we have a couple of other calculators that might help you.

Sample size which is the number of people that will be interviewed. Population that can be left blank if population in infinite or can be provided as a finite value; Pick certain choice % refers to the percentage you expect people to pick up a certain choice from the possible answers.

Today we have decided to provide free Score Chart to all of you. You will be surprised that printing and saving of chart and table available on this site are entirely even you could share with your friends as much as you want.
