Question

With the data collected, Dr Tian ran a test to see if there was a significant difference in the mean of X (a factor affecting the continued usage of e-learning communication) between male and female students. Take s12042516 as an example.

Suggest the test that should be used and explain your reason. State the independent and dependent variables, underlying null and alternative hypotheses.
Interpret the result and explain whether there is a significant gender difference.
Based on the result and the choice of your X, suggest whether Dr Tian should use two different ways to motivate male and female students to use e-learning communication, respectively.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
