UNGROUPED DATA For number 2 find (a) the mean, the median a) and the mode of the ungrouped data. 2) Earthquake Strengths. Twelve major earthquakes had Richter magnitudes shown here. 7.0, 6.2, 7.7, 8.0, 6.4, 6.2, 7.2, 5.4, 6.4, 6.5, 7.2, 5.4 For number 3 answer k by following the instructions from a to e 3.) The Newly-Hired Crew. If at the end of the month, Sonya's Kitchen hired another crew member whose age is 22, ther data now consists af elght ages: 18, 20, 18, 19, 21. 18, 47 and 22, an even number. How many middle entries are there? Try to find out by followtng these stmple steps: a. Arrange the crew's ages in numerical order. b. Find the two mlddle values (ages). c. Get the average of the two middle values. d. is now the median age? e. How many are below this age? above this age?
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.
