Report
AI Summary
This report presents a statistical analysis of several psychological constructs. The analysis begins with reliability tests using Cronbach's alpha to assess the internal consistency of variables related to skills, emotions, participation, and academic performance. High alpha coefficients across the board indicate excellent internal consistency, suggesting that the questionnaire items measure the same underlying concepts consistently. The report then moves on to regression analyses, examining the relationships between various factors and outcomes such as academic performance and word of mouth. Several models are tested, incorporating variables like skills, participation, and emotions, and exploring moderation effects of age, gender, and network size. The findings reveal that participation consistently emerges as a significant predictor, while the influence of emotions and skills varies depending on the model and moderating variables. The report highlights the importance of considering moderating variables in understanding complex relationships between variables.

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.

Regression: Word of Mouth (model 3)
The regression model is a linear model that can be used to predict the word of mouth using skills
of a student, participation and emotion. Based on the results, only one variable is significant in
the model. The only variable that is significant is the participation (p=0.00<0.05. on the other
hand, emotion (p=0.969) and skills (p=0.074), which are both greater than 0.05. When age is
used as a moderator in the regression model, both skills (p=0.754) and emotion remain
insignificant while participation (p-0.00) remain significant in the regression model. However,
we can see that the addition of age variable has led to a change in the level of insignificance of
the two variables. The use of either gender or network as the moderator variable has similar
effects as age (Jose & Joaquim, 2016).
Introduction of network size as the moderating variable to the model lead to a significant change
in the significance values of the model constants. With network size as the moderating variable,
on participation is significant in predicting word of mouth, with p=0.00<0.05. on the other hand,
emotion (with p=0.934) and skills (with p=0.830) are all insignificant in the model. Therefore,
network size is a moderating variable in the model for predicting word of mouth of a student.

Regression: Student satisfaction
The regression model to predict the level of student satisfaction with online learning using skills,
participation and emotions show that only emotion (p=0.073) is insignificant. On the other hand,
both skills and participation are significant in the model. Using age as a moderator variable for
the multiple linear model reveals that there is no much change in the results in terms of the
significant variables and the insignificant variables (Cristina, et al., 2016). Using gender as the
moderator reveals that only emotion is insignificant. Moreover, the p=value as reduced.
Therefore, we can conclude that gender is a moderating variable in a multiple linear model for
predicting the level of students satisfaction using skills, participation and emotions (Kai &
Baoding, 2018). With the network size as the moderating variable, there is no change in
significance of skills and participation. The significance of skills and participation remains the
same, p=0.03 and 0.00 for skills and participation respectively. On the other hand, there is a
slight change in the significance of emotion from p=0.754 to p=0.078. Therefore, we can
conclude that network size is not a moderating variable in the model for predicting the
satisfaction of the students with online learning.
