Some experimental data for a distance measurement are as folows: Data Point | Value Measured in meters 1.52 1.49 1.50 1.56 1 2 3 4 5 1.54 1.38 |1.61 |1.55 1.54 8 10 11 12 1.62 1.81 1.47 1.52 13 14 1.44
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.
- Calculate the standard deviation and the standard deviation of the
mean .
- Calculate the absolute uncertainty, fractional uncertainty, and percentile uncertainty
