Find the expected count and the contribution to the chi-square statistic for the (C,E) cell in the two-way table below. D E F G Total A 38 33 39 37 147 B 72 94 67 57 290 C 17 38 25 27 107 Total 127 165 131 121 544 Round your answer for the expected count to one decimal place, and your answer for the contribution to the chi-square statistic to three decimal places. Expected count =? contribution to the chi-square statistic = ?
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.
