What are the steps for finding the relative frequency of sample means above or below a specified mean?
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
What are the steps for finding the relative frequency of sample means above or below a specified mean?
The sampling distribution of sample means is approximately a normal distribution because of the application of central limit theorem'.
1. When raw scores are large in number, the distribution is going to follow a normal distribution.
2. The mean is going to be similar to the population mean
3. The standard error of the sampling distribution of sample means is going to be
