Company a has 6 employees whose salaries per month are the following : 2 clerks have a salaries of 13,500 pesos, 1 executive secretary with a salary 25,000 pesos, 1 janitor with a salary of 8,000 pesos, 1 accountant with a salary of 28,000 and 1 manager with a salary of 50,000 pesos. A. Determine the mean salary employees per month and compute for the median and mode. B. Find the percentile rank of a salary of 25,000 pesos. C. Find the value corresponding to the 3rd Quartile and 7th decide. D. Find the degree of soreness and kurtosis. E. Determine the MAD, variance and standard deviation of the salaries of the employees.
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.
