Consider the following population of ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. a. Find 3 random samples of the five digits from the list. Record the elements of each sample. b. find the arithmetic average of each sample. (Hint: to find the average, sum the data enteries and divide the sum by the number of enteries in the sample.) there is a line over each of these x1 = x2= x3= c. comment on how your results compare with the average of the entire population.
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.
