Calculating Confidence Interval for Lab 2 #54

Closed dmkoch9978 closed 1 month ago

dmkoch9978 commented 2 months ago

Hello,

For lab 2, do we need to actually calculate the confidence interval for Q2-4? I used the visuals for my answers but it's just now occurring to me that I may actually need to use the equations we've been given in lecture.

Thanks, Dani

@dmkoch9978 it's important that you understand the underlying math for calculating confidence intervals from slope and SE. I recommend using the formulas from the lecture and showing your work.

@nickmcmullen Besides the RMD/HTML, may we do the calculations by hand and import as PDF to show the math?

nickmcmullen commented 2 months ago

@pathernz that's fine, but you shouldn't need to. You can just type the values into the formula to show you understand how to use it.

Hi Im also having trouble how to write the formula in R

nickmcmullen commented 2 months ago

@jteles24 @pathernz You both are comfortable with the below formulas from the lecture notes. And you know the values from the model tables, so just plug them in to calculate the confidence intervals.

Upper bound = b1 + SE(t) Lower bound = b1 - SE(t)

Thank you very much

very confused on question 5 not clear to me

nickmcmullen commented 1 month ago

@jteles24 the lab RMD template has a more specific question in Q5 with regard to slope and SE for the three models you drew CIs in Q2-4

nickmcmullen commented 1 month ago

@dmkoch9978 now that Lab 02 has passed can you close this issue out to keep the forum tidy? Thanks!
