The following data show the number of hours spent watching television for 10 randomly selected freshmen attending a liberal arts college in the Midwest. Hours of Television Viewed Weekly 15 14 19 17 13 18 16 19 15 15 - Calculate the range, variance, standard deviation, and interquartile range for the sample data. The range for the data set is O. (Type an integer or a decimal. Do not round.) The sample variance, s², is (Round to two decimal places as needed.) The sample standard deviation, s, is (Round to two decimal places as needed.)
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.
