The manager of an electronics company conducted a study on the estimated annual profit that the business could earn, in line with its plan to launch a new product to the market. According to the results, the company could earn an annual profit of PHP 6.7 million if aggressive selling is applied; PHP 4.9 million could be the profit if the manner of selling is normal; and a loss of PHP 1.3 million if selling is easygoing. Assuming that there are 17 aggressive sales agents, 27 average agents, and 9 lazy sales agents, what is the standard deviation?
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.
