Now, enter the values appropriately and accordingly for the parameters as required by the value (x) is 4, mean (μ) is 20 and standard deviation (σ) is 26.Īs you can see from the screenshot above, Nickzom Calculator– The Calculator Encyclopedia solves for the standard normal variable and presents the formula, workings and steps too. The screenshot below displays the page or activity to enter your values, to get the answer for the standard normal variable according to the respective parameters which are the value (x), mean (μ) and standard deviation (σ). Now, Click on Standard Normal Variable under Probability Once, you have obtained the calculator encyclopedia app, proceed to the Calculator Map, then click on Probability under Mathematics. To get access to the professional version via web, you need to register and subscribe for NGN 1,500 per annum to have utter access to all functionalities. You can get this app via any of these means: To get the answer and workings of the standard normal variable using the Nickzom Calculator – The Calculator Encyclopedia. First, you need to obtain the app. Nickzom Calculator – The Calculator Encyclopedia is capable of calculating the standard normal variable. Therefore, the standard normal variable is -0.615.Ĭalculating for Value when the Standard Normal Variable, the Mean and the Standard Deviation is Given.įind the value when the standard normal variable is 12, the mean is 10 and the standard deviation is 4.Ĭalculating for Mean when the Standard Normal Variable, the Value and the Standard Deviation is Given.įind the mean when the standard normal variable is 6, the value is 30 and the standard deviation is 3.Ĭalculating for Standard Deviation when the Standard Normal Variable, the Value and the Mean is Given.įind the standard deviation when the standard normal variable is 8, the value is 40 and the mean is 8. Standard normal distribution: a normal distribution with mean of zero and standard deviation of one. The formula for calculating standard normal variable:įind the standard normal variable when the value is 4, the mean is 20 and the standard deviation is 26. To compute for standard normal variable, three essential parameters are needed and these parameters are value (x), mean (μ) and standard deviation (σ). The image above represents standard normal variable.

Critical Value is the value that a test result must exceed in order for the researcher to conclude that the treatment or intervention he applied has a significant effect on the variable being investigated. What is the standard normal distribution table? A standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of Φ, which are the values of the cumulative distribution function of the normal distribution. It is represented as z a, where the alpha level, a, is the area in the tail. A z critical value is used when there is a normal sampling distribution, or when close to normal. A critical value is a line on a graph that splits the graph into sections. What is the formula for critical value? Formula Used: Probability (p): p = 1 - α/2. Negative binomial distribution Probability distribution. Critical values determine what probability a particular variable will have when a sampling distribution is normal or close to normal.
