I have a dataset with 15 people. For each person I have the age and a blood measurement. The relation between the age and the blood measurement is linear.
The plot between the two variables looks like this:
I would like to make a model in which I can predict the blood measurement given that I know the age. If I have a different dataset and I know the age of those people I can therefore predict their blood measurement.
Can anyone help with that?
Can I use the equation y=ax+b? Would that work for a different population?

Of course your dataset is awfully small. But if it only an exercise, you could indeed make a linear model. I'm guessing you're using Excel or a similar program to plot the data - I'm sure that there's a functionality to calculate the equation of the line too. Otherwise, you can read this : en.wikipedia.org/wiki/Linear_regression

Thanks for your answer. Yes I am using Excel and I am able to calculate the intercept and slope of the linear equation y=ax+b. My question is: If I use that value of intercept (b value) and slope (a value) derived from this dataset can I then substitute the x-values from a different dataset to predict y?

It is not an actual research given the very small sample size. It is a university assuagement (foundation level)
