A team of researchers are interested in the association between age (in years, the explanatory variable) and systolic blood pressure (mmHg, the outcome variable). The results of a simple linear regression of systolic blood pressure (sbp) on age are provided in the following output.

What is the interpretation of the coefficient for age?

Question

A team of researchers are interested in the association between age (in years, the explanatory variable) and systolic blood pressure (mmHg, the outcome variable). The results of a simple linear regression of systolic blood pressure (sbp) on age are provided in the following output.

What is the interpretation of the coefficient for age?

Answer

For each 1 mmHg increase in systolic blood pressure, there is an associated 0.86 year increase in age

Answer

The correlation between age and systolic blood pressure is 0.86

Answer

For each one-year increase in age, there is an associated increase in systolic blood pressure of 0.86 mmHg

Answer

There is no evidence of an association between age and systolic blood pressure (P=0.86)
