Data Analysis and Modeling for Fitness Application: Assignment

This assignment solution details the application of various statistical methods for analyzing data related to a fitness application. The analysis employs SEM (Structural Equation Modeling), GLM (Generalized Linear Modeling), and multilevel modeling. The document outlines the coding process for data preparation, followed by the collection of data pertaining to standard deviation, variances, average, and median from control, user, and competitive feedback groups. Regression analysis is used to determine the interdependency of variables, and the impact of external factors like weather. ANOVA is used to test hypothesis 3. Correlation analysis is used for hypothesis 4. Finally, regression analysis is used again for hypothesis 5. Each section highlights the specific methods used, extra parameters considered, and model improvement techniques, such as multicollinearity analysis. References to relevant academic sources are also included.

Q 1.1
To conduct the study, SEM and GLM and Multilevel modeling as an analytical method
are used.
Q 1.2
Before running any analyzis, Coding is perform for the easiness of work.
Q 1.3
In this, data pertaining to standard deviation, variances, average and median will be collected
about control, user and competitive feedback group.
Q 1.4
For conducting the test, Regression analysis is used that will help to determine the
interdependency of the two variables and by developing the fitness online application will assist
to examine the interdependency of two variables (Schroeder, Sjoquist and Stephan, 2016).
For this, rain and weather are also taken as a parameter for the study in order to conduct
it in better manner.
For model improvement, Multicolinearity analysis is used that in which different factors
are also added in order to get the better response.
Q 1.5
For test the hypothesis 3, Anova is used which clearly determine the hypothesis is
accepted or rejected such that it is actually used to examine the statistically significant difference
between two or more independent variable (Leonzio, 2019).
For extra parameter, some of the people are selected who regularly go to gym. So this
will help to collect the data better manner.
Multicolinearity analysis, is used as a model improvement against the previous model.
No, there is no specific decision or choice need to make.

Q 1.6
For hypothesis 4, correlation analysis is used that change the value of one variable to the
another such that when there is a negative variable that means one value increases while another
is decreases and vice versa (Reimann and et.al., 2017). Such that if the correlation is comes
positive which means there is a positive relationship with the number of steps taken on the
subsequent days.
For the extra parameter, pearson is used that will help to generate the best results and
gain better outcomes.
Process correlation analysis is used as an improvement model that is used against the
correlation test under Multilevel analytic model.
No, there is no specific changes needs to make under the hypothesis 5
Q 1.7
For hypothesis 5, regression analysis is used that will help to analyze the relationship
between two variables.
P is used as an extra parameter for this hypothesis.
For model improvement, Multicolinearity analysis is used against the previous model.
By proper coding, the estimated change over time in steps for the each group.
Q 1.8
Increase is number of steps as per weather is likely to be flawed because the demand of
customers is continuously changes as per the weather changes and that is why, this hypothesis is
consider as likely to be flawed.
Q 1.9
By using regression tool, hypothesis 2 is change the analysis and get the results. Such that
earlier, this tool is used because it describe the relationship between two variables or more.
