lmege. mputes both the mean and median family income across all students and is surprised at the mean income is much higher than the median income. What is the most likely rea r the difference in the mean and the median? elect one: The sample size is too small. The median tends to produce lower estimates of central tendency. The median is not an appropriate estimate for annual family income's level of measure correct The mean is more affected by a small number of extreme values.
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.
