Question

Think about a healthcare scenario where multiple regression might be useful in a healthcare organization. Consider what your dependent and independent variables might be for conducting a multiple regression analysis. Build a small example, and run the regression analysis.

Post a description of the dependent and independent variables you will use for your multiple regression analysis, and then explain your regression model in terms of your dependent and independent variables. Explain how you might measure your variables. Be specific and provide examples.

How might you measure variables-

Answer 1

Scenario: Effect of certain variables on Blood pressure of 10 individuals

Dependent variable: Blood pressure

Independent variable : Age,Sleeping hours ,weight

Bp is measured using BP machine , weight using weighing message , age and sleeping hours got from the individual

Data :

BP	AGE	WEIGHT	SLEEPING HOURS
96	25	63	7
132	42	81	8
111	28	53	6
82	66	69	6.5
121	89	54	8.5
98	52	49	7
107	16	48	8
116	46	98	6
135	76	55	6.5
79	34	87	5.5

The regression equation is given as BP = 35.223+0.192(AGE)+0.431(WEIGHT)+8.199(SLEEPING HOURS)

For an individual of age 56 weighing 78 and sleeping for 8 hours ,then the predicted BP is given as 120
