Analyzing the Relationship between Health Conditions and Lifestyle Factors

This article analyzes the relationship between health conditions and lifestyle factors such as smoking, exercise, energy levels, and eating habits. Regression analysis is used to predict the impact of these factors on overall health.

Executive summary:
It is a problem to check the health condition of a group of people and the factors that affect their
health conditions. The fact will be tested here through data analysis. It can be predicted here that
the variable like smoking conditions, exercise conditions and others are closely related to the
health conditions.

Introduction:
It is a problem to check the health condition of a group of people and the factors that
affect their health conditions. It is a general believe that smoking habits, exercise and other
things are responsible for s person’s healthy state. The fact will be tested here through data
analysis.
Analysis:
Given is the dataset on health conditions and the factors related to health. The factors in
the dataset are smoking conditions, meal habits, exercising habits, work pressure, depression
levels, and reaction to stress, weather conditions and lots more. The given problem is to find the
relation between healthy conditions and smoking habits, exercise, energy levels and eating three
meals a day (Carroll, (2017). The dependent variable here is health conditions and the rest are the
independent variables. Regression line can be predicted here as:
y = a + b*x1 + c*x2 + d*x3 + e*x4 , where x1, x2, x3, x4 are the
independent variables and y is the dependent variable and a, b, c, d
and e are the regression co-efficient.
Testing hypothesis will be :
H0: It is a bad fit or β = 0.
VS.
H1: It is a good fit or β ≠ 0.
The analysis, calculation and interpretation are done below:

Given that the regression statistic value is 66.183 and f significant value is 0.001293 which is
smaller than the f statistic value (Polanczyk et al., (2014). Therefore, the null hypothesis will be
rejected here and it can be said that the regression fit is a good fit. And the regression line can be
stated as:
y = 4.525 + (0.401)*x2 + (0.434)*x3 + (0.105)*x4 , where x1 is the smoking
habit and y is the health condition as the rest of the coefficients will get rejected here.
Statistical interpretation:
Significance level is the probability of rejecting the null hypothesis when, in fact, it is
true. Again, p-value or the calculated probability refers to the probability of searching for
observed or other results in case when the null hypothesis is true.
0.278 part of variation can be explained here and the rest of the 0.722 part remains
unexplained.
VIF levels describes the level of co-linearity and a co-linearity level of more than 10 can
be described as dangerous and can effect prediction in a wrong way. The variables and their VIF
levels are: VIF of smoking habit = 1.024, VIF of Exercise = 1.253, VIF of Energy levels = 1.178
and VIF of Eating 3 regular meals a day = 1.079. It can be predicted here that all the variables
depicts a certain level of co-linearity but they are within the tolerable limit.
Conclusion:
It can be predicted here that the variable like smoking conditions, exercise conditions and
others are closely related to the health conditions.
