Determine if a data set is skewed Question Which of the following frequency tables show a skewed data set? Select all answers that apply. Select all that apply: Value Frequency Value Frequency 4 1 2 5 2 1 11 3 30 7 7 8 19 3 22 9 17 4 15 10 17 12 11 15 6 6. 12 12 7 1 13 4 8. 1 14 1 15 Value Frequency Value Frequency 1 13 1 4 14 6 1 6. 15 9. 7 9. 16 15 8. 12 9. 12 17 27 10 18 18 28 11 12 12 17 19 10 13 11 20 4 14 15 1 16 17 1 5.
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.
I don't know how to look at a frequency table and see which ones are skewed.
