Suppose that a standard mass is measured 30 and the calculated values of a = standard error of mean = 0.08 and s = standard deviation = 0.43 for a normal distribution. If the instrument is then used to measure an unknown mass and the reading is 105.6 kg, what is the error of the reading at 95% confidence? %3D %3D %3D a = 0.08 S = 0, 43 n= 30
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.
