A small warehouse employs a supervisor at $1350 a week, an inventory manager at $800 a week, six stock boys at $420 a week, and four drivers at $520 a week. Assignments Gradebook c) Which measure of center best describes a typical wage at this company, the mean or the median? O A. The median best describes the typical wage. The mean is not a good measure of center because it is affected by the two higher salaries. StatCrunch O B. The median best describes the typical wage. The mean is not a good measure of center because it is affected by the multitude of duplicate salaries. eText Content O C. The mean best describes the typical wage. The median is not a good measure of center because it is affected by the multitude of duplicate salaries. O D. The mean best describes the typical wage. The median is not a good measure of center because it is affected by the two higher salaries. Study Plan d) Which measure of spread would best describe the payroll, the range, the IQR, or the standard deviation? Why? Video & Resou Library O A. The standard deviation is the better measure of spread. Neither the IQR nor the range account for every data value. O B. The IOR is the better measure of spread. The standard deviation and the range are both affected bydthe two higher salaries. Accessible Res O C. The standard deviation is the better measure of spread. The lQR and the range are both affected by the two higher salaries. Purchase Opti O D. The range is the better measure of spread. Neither the IOR nor the standard deviation account for the extreme values. Communicatic Click to select your answer(s). Next
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.
