How big of a factor is age in determining adoption time? |
Question Type (circle one): Lookup Arithmetic Statistical |
|
all animals at the shelter name, age, and weeks |
|
|
Set y-axis to weeks, set x-axis to age. Select least squares line from the Measure menu. |
|
|
The slope is positive (0.789) and R=0.448, so there is a moderate, positive relationship
Is weight a bigger factor?

I performed a linear regression on a sample of animals at the shelter[dataset or subset] and found a moderate (R=.448), positiveweak / strong / moderate (R=…), positive / negative correlation between age[x-axis] and time to adoption[y-axis]. I would predict that a 1 year[x-axis units] increase in age[x-axis] is associated with a .789 week[slope, y-units] increaseincrease / decrease in time to adoption[y-axis]. |

I performed a linear regression on a sample of [dataset or subset] and found a weak / strong / moderate (R=…), positive / negative correlation between [x-axis] and [y-axis]. I would predict that a 1 [x-axis units] increase in [x-axis] is associated with a [slope, y-units] increase / decrease in [y-axis]. |
