INTRODUCTION
Regression analysis assist in identifying the relationship between the variables. This
assignment will include the analysis on the basis of which the relationship between the variables
will be identified that will help the company is changing their assessment criteria.
TASK
Research question
 What is the relationship between performance and metacognition ?
 What is the relation between performance and leadership?
 What is the relationship between performance and social skills?
 What is the relationship between IQ and performance
 What is the relation between performance and motivation?
The linear regression method is chosen for the analysis because it assist in identifying the
level of relationship existing between the variables.
Hypothesis 1 :
H0 = There is no significant relationship between IQ and performance
H1= = There is significant relationship between IQ and performance

a. Dependent Variable: Performance
Interpretation : From the hypothesis it has been identified that there is significant relationship
between the variables because the p value determined 1 less than 0.05. The modal summary
provided information that the relationship between the variables is equal to 63.8% which
shows that the is significant relation between the variables. As per the ANOVA table is it is
shows that the significance level is less than 0.05. So, it can be said that the IQ have as
significant relationship with performance (Shipman, 2017).

Interpretation : As per the Hypothesis 2 it is understood that that there is significant relation
between the variables as the p value is lower than 0.05 and the modal summary provide the
value of R as 63.4% which shows there is Signiant relationship between metacognition and
performance (Goodwin & Goodwin, 2016).

Interpretation: From the above it can be interpreted that there is significant relationship
between the variables as shows by the Modal summary (Walliman, 2017). It shows that the
value of R square is equal to 38.8% which means there is relationship existing between the
variables upto this percent.

a. Dependent Variable: Performance
Interpretation : It can be interpreted that there is significant relationship between performance
and motivation but the value of square indicate that there is less relationship existing
between the variables which is about 10.4%. The significance level as shown by the
coefficient is lower than 0.05 which means there is significant relationship existing between
the variables (Jackson, 2015).

a. Dependent Variable: Performance
Interpretation : From the above data it can be interpreted that there is significant
relationship existing between the variables. There is less relationship existing between the
variables as shown by the value of R square which show that the variables is 6 % related to the
other variable.
Modal summary: It provide information about the level of relationship existing between the two
variables. The R value shown in the Modal summary provide that there is significant
relationship between the variables (Howitt, 2016).
ANOVA: The tables shown in the regression analysis provide information that there is variation
existing the observation (Beins & McCarthy, 2017). It is the analysis of variance which is
used to identify the difference between the two or more means.
 Coefficients: It is used to show the relation between the two variables which are used for
the hypothesis test.

From the above it can be interpreted about Correlation at 0.01 about the relationship
between the different variables. It shows that performance is related to every variable but there
are variables which are not significantly related to each other.

J) It is concluded based on the research that the predictors assist in predicting the work
performance. It means if there is any changes in the predictors the performance will also be
changed. As per the report which state about the regression analysis provide that the
variables are significantly related to each other (Coolican, 2017). Regression analysis assist
in identifying the relationship between the variables. It has included the linear regression
analysis to identify the relationship between the variables.
CONCLUSION
From the above assignment, it has concluded about the regression analysis which assisted in
identifying the relation between the different variables. It is suggested to the company that if
there is any changes in the variables than the work performance will be affected so it is
suggested that the variables which has shown the least relationship consist of social skills,
motivation and leadership which have the lower relationship with performance as compared to
13

metacognition. It is suggested that the company should focus on this variables to improve the
performance.
