I used a correlation coefficient calculator and it said that the coefficient was -0.04. So this means that the type of correlation is negative, but is it strong or weak???

@mathmate @agent0smith do you guys know this?

agent0smith · Answer

Correlation coefficients close to 0 are weak. Close to 1 or -1 are strong.

mrs.jackskellington · Answer

thank you, can you help with another part to this question

mathmate · Answer

and positive correlation means the slope is positive, 
negative correlation for negative slope.

mrs.jackskellington · Answer

What is the value of the slope of the graph of velocity versus time between 10 and 20 minutes, and what does the slope represent?

agent0smith · Answer

You'll have to estimate the slope, I'm sure you can. Use slope formula or estimate from the graph.

The slope of a velocity time graph gives you acceleration.

mrs.jackskellington · Answer

ok

mrs.jackskellington · Answer

I got that the slope is 0.06. thx for everything!

agent0smith · Answer

Looks reasonable.
