Results and Interpretations
Reliability is a statistical test that is used to investigate the level of internal consistency among
variables of a categorical scale. The value of reliability ranges between 0 and 1. The value of the
coefficient of reliability increases either with the increase in the number of variables or with the
increase in inter-correlations (Fokkema, et al., 2017).
Reliability: Skills
The results of reliability test of the skill variables are shown below. The Cronbach’s alpha
coefficient is 0.933. The coefficient is greater than 0.9, implying that the variables have excellent
level of internal consistency or reliability. For example, student who strongly agrees with
studying on a regular basis is also highly likely to strongly agree with keeping up with learning
materials (Radakovic, et al., 2019). Similarly, a student who strongly agrees with listening
and reading carefully online information is also highly likely to strongly agree with taking good
notes over reading power point presentations.

Reliability test: Emotion
The Cronbach’s alpha coefficient of reliability test for emotion is 0.898, which is a good level of
internal consistency. The level of consistency demonstrate that the variables are highly inter-
correlated. The level of internal consistency demonstrated show that students are most likely to
respond to the questions in a similar or consistent manner (Cypress, 2017). For example, a
student who strongly agrees (disagrees) with putting more efforts when studying is also highly
likely to strongly agree (disagree) with being more motivated to learn via social media.
Similarly, a student who strongly agrees with applying course materials to daily life is also
highly likely to strongly agree with finding ways to make course materials relevant.

Reliability: Participation
The Cronbach’s alpha coefficient of reliability test is 0.923, indicating that the variables have an
excellent level of internal consistency. Therefore, the students were consistent in answering
questions related to participation (Pushkarev, et al., 2018). For instant, a student who
strongly agrees to having fun in online chats or discussions is also highly likely to strongly agree
to engaging in online conversations. Similarly, a student who strongly agrees with posting
regularly in forums is also highly likely to getting to know other students.

Reliability test: Academic Performance (model 1)
The students were highly consistent in answering the questions about academic performance as
demonstrated by the reliability test. The Cronbach’s alpha coefficient demonstrates that there
was a good level of internal constancy (alpha=0.883) between the questions about academic
performance (Cypress, 2017). The good level of internal consistency reveal that a student who
strongly agrees to be doing well in online tests is also highly likely to strongly agree to be getting
good grades.

Regression (moderation effects)
A moderator is a variable that detects the conditions under which a predictor variable predicts the
outcome. In other words, a moderator explains when a dependent variable is predicted by the
independent variable.
Regression: Performance (model 2)
In a multiple linear regression model for predicting academic performance of a student based on
their corresponding skills, participation and emotions, it is clear that both skills and emotions are
significant in the model (p=0.00<0.05). However, the results demonstrate that the emotion of
student is not significant in predicting the academic performance of a student (p=0.794>0.05).
The first moderation is to add the corresponding age of the student as a moderator variable. With
age as the moderating variable, the results have little change (David & Liron, 2016). Emotion
of a student still remain insignificant in predicting the academic performance of the student while
skills and participation is significant. Therefore, age is not a moderating variable in the linear
model.
The second moderation is gender. With gander as the moderator, we have similar results.
However, the level of insignificance of emotion has increased to 0.95. Therefore, we can
conclude that gender is a moderating variable in a regression model to predict the performance of
a student using the corresponding skills, participation and emotions. Gender is a moderating
variable for emotions.
The introduction of network size as the moderation variable has led to a change in the
significance of the variables. Participation and skill remained significant with values of 0.00
(p=0.00<0.05). On the other hand, emotion remained insignificant in predicting academic
performance of a student, with p=0.091 (p=0.091>0.05). Since the introduction of network size
led to the change in the significance of the variables, we can conclude that the network size is a
moderating variable.
