do online students perform differently than students in a traditional classroom? Las semester there was 100 students registered for the online version of a statistics course, and 100 Students registered for the traditional classroom version. All students took the smae final exam. Suppose the group of online students had a mean exam score of 75 with a standard deviaiton of 3. The group of classroom students had a mean exam score of 76 with a standard deviiton of 4. Do the sample data provide evidene that there is a difference in the average exam scores between the two groups? Test the relevant hypotheses at a significance level of a=0.05.
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.
