Suppose you have a data set of size 26, with mean 50 and standard deviation 8. If you subtract 8 from every data value, how will the mean and standard deviation change? The mean and standard deviation will both stay the same. The mean and standard deviation will both decrease. O The mean and standard deviation will both increase. 2 The mean will decrease and the standard deviation will increase. O The mean will increase and the standard deviation will decrease. ill docroace and the standard deviation will stay the same.
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.
