Results:

From the above descriptive it is clear that males are more avid coffee drinkers than females.

Males tend to prefer more coffee than females, as more males prefer coffee every day as compared to females.

Similar statistics for other variables are shown below:

SPSS AnalysisResults:  More males feel that sleepiness decreases because of coffee. Same is the case for alertness. However more females feel that there is memory improvement experienced on coffee consumption.

The results can also be visualized as per the following graphs:

The gender based analysis reveals that for Q1    “How many years have you been an avid coffee drinker” the males are more avid coffee drinkers than females.

The case processing summary for the above graph is presented below:

Case Processing Summarya

How many years have you been an avid coffee drinker?  * Male =1 Female = 0 15 100.0% 0 0.0% 15 100.0%

a. Limited to first 100 cases.

Then, we have another graph which reveals about the other parameters:

Again, based on the graph we see that the males’ response to the question, “How many times do you consume coffee during a day?” is more than females. This means that males drink more coffee per day than females.

Similarly, we have another graph as follows:

The graph reveals the information for the following questions:

After having coffee do you experience tiredness after some time?
Do you experience your sleepiness decreased after consumption of coffee?

We see that bars are taller for males as compared to females for both the questions. This means that males feel more active after drinking coffee, though they feel tiredness after some time.
