In what sense is the mean teh center of distributon? a.M is the center because half the sample scores are always above it and half are below b.M is center because it is always the most probable score in the sample c.M for the sample always equals micro for the population d.M is like a balance point because E (m-x)=0 for every sample.
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.
In what sense is the
a.M is the center because half the sample scores are always above it and half are below
b.M is center because it is always the most probable score in the sample
c.M for the sample always equals micro for the population
d.M is like a balance point because E (m-x)=0 for every sample.
The mean is is the centre of the distribution because mean is based on all the observation.
The sum of deviations from the mean always equals to zero.
