The waiting times of eight (8) patients to be seen in a medical office, expressed in minutes, were as follows: 34, 56, 48, 29, 33, 44, 51, 65. Calculate the following: range, variance and deviation standard.
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.
Question # 4 The waiting times of eight (8) patients to be seen in a medical office, expressed in minutes, were as follows: 34, 56, 48, 29, 33, 44, 51, 65. Calculate the following:
For the data provided for 8 patients.
Range for the data is given by,
Range = Highest value – Lowest value
= 65 – 29
= 36
To calculate variance and standard deviation,
