Z score normal distribution table spm. So when you are checking one of these z score tables and you have a positive z score you will need to sum 0 5 or 50 to calculate the area that is to the left of the z score. In the above example we derive that eric s z score is 0 56. A standard normal table also called the unit normal table or z score table is a mathematical table for the values of ϕ indicating the values of the cumulative distribution function of the normal distribution. Since probability tables cannot be printed for every normal distribution.

So in this case it would be 0 5 0 3621 0 8621 as you can see both values are identical no matter if you re using one z score table or another. 8 2a z score of a normal distribution example. A p z 0 600 b p z 1 24 c p z 1 1 d p z 0 76 solution. Where x is a score from the original normal distribution μ is the mean of the original normal distribution and σ is the standard deviation of original normal distribution.

B the masses of form 5 students of a school are normally distributed with a mean of 60 kg and a standard. Calculate the standard score of the value x 35. Find the value of each of the following probabilities by reading the standard normal distribution tables. Z score also known as the standard score indicates how many standard deviations an entity is from the mean.

Once you have the z score the next step is choosing between the two tables. 8 2b standard normal distribution tables example 1 example 1. A a normal distribution has a mean µ 50 and a standard deviation σ 10. Standard normal distribution table when reading the standard normal distribution tables it.
