Using the following data, what is the probability you'd select an individual whose IQ is greater than 90 but less than 95? IQ raw data: 100 91 65 96 102 105 100 125 115 102 100 71 85 122 90 108 101 105 100 89 114 109 111 135 mean - 100.5. median - 101, mode - 100 range - 70, variance - 256.76, standard deviation - 16.02
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.
