Regression Model Input Formats

When calculating the predicted output of a regression model, I often struggle with inputting the independent variables in the correct format. In this instance (Reading 10, practice problem 4) I am asked to input a 1% decline in NASDAQ spreads and input it as 0.01. Referring to the solution, I can see that this should have been input as 1 not 0.01.

If the question phrases the independent variable as “Percentage decline in NASDAQ spreads”, can I safely assume that I should input a percentage as an integer rather than a decimal? How can I decide which format is correct? In this case using the decimal input 0.01 gave a decline in spreads of about 15% compared to the correct 45% decline in spreads so a common sense approach to the answer doesn’t help.

I had the same issue with this question.

The question is worded stupidly.

Ignore it.

On the real exam, if you have to use the values of the independent variables, they’ll make it abundantly clear whether you’re supposed to use 1 or 0.01.

Thanks

You’re welcome.
