Hello, I am completely stuck on finding frequency distributions. I do not understand the process can you please help me?? I need to find frequencies for the following BMI's: 15.0-20.9; 21.0-26.9; 27.0-32.9; 33.0-38.9; 39.0-44.9 Here is the data set: 17.7 28.7 19.2 27.9 33.5 23.2 22.4 44.9 26.5 18.3 24.7 31.8 23.8 28.6 37.7 28.5 23.8 21.5 31.3 23.5 Thank you and my apologies.
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.
