The given data represents a frequency distribution of the F-scale intensities of recent tornadoes. Use the frequency distribution to construct a frequency polygon. Does the graph suggest that the distribution is skewed? If Tornado F-Scale Frequency so, how? 0. 24 19 Construct a frequency polygon using the data. Choose the correct graph below. O A. OB. OD. Frequency Frequency 30 Frequency 30 30 30 kouanbasy -1 -1 -1 5. F-Scale F-Scale F-Scale F-Scale Does the graph suggest that the distribution is skewed? If so, how? O A. The distribution appears to be skewed to both sides.
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.
