Janet measured 5 solutions of contact lens cleaner and measured the amount of solute in each solution. The results are: 80 mg, 90 mg, 92 mg, 94 mg, 96 mg How will the removal of the lowest measurement affect the mean and median? A, B, C, D? A. Both the mean and the median will decrease, but the mean will decrease by more than the median. B. Both the mean and the median will decrease, but the median will decrease by more than the mean. C.Both the mean and the median will increase, but the mean will increase by more than the median. D.Both the mean and the median will increase, but the median will increase by more than the mean
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.
