an r value of 1 would be a graph that has a linear line going up one then
to the right one so the closest to that is the 2nd graph (B)
Graph 2) is the correct answer.
We know that:
r = -1 is strong negative correlation and 1 is strong positive correlation. 0 means no correlation.
Hence by the values of these r we can characterize our function.
Now in this question we are given that:
The graph shows data whose r-value is most likely closest to 1?As the graph 1) is a decrease in the values hence it shows a negative correlation i.e. r= -1. similar is the case for graph 3).Also the graph 4) is distorted i.e. it shows no correlation i.e. r=0.
Hence all the remaining three options are discarded.
Hence option 2) is true.
I.e. graph 2) represents a strong positive correlation i.e. r-value is closest to 1.
Ik I’m late but C on edge
Since you didn't put a picture I don't know if this is right, but I saw that another person had answered a question with similar wording, hope this helps.r = -1 is strong negative correlation 1 is strong positive correlation. 0 means no correlation.This here graph represents a strong positive correlation because it's r-value is closest to 1.
Hope this helps, have a BLESSED and wonderful day! :-)
The first graph.
Correlation coefficients, or r-values, range from -1 to 1. An r-value of -1 means the dependent variable decreases as the independent variable increases; it also means the data is perfectly linear. An r-value of 1 means the dependent variable increases as the independent variable increases; it also means the data is perfectly linear. An r-value of 0 means there is no correlation between the two variables.
In the first scatter plot, the data is scattered throughout the graph. There does not appear to be any pattern at all; this would be an r-value of 0.
In all three of the other graphs, the data appears to be linear; this would not be an r-value of 0.
The first one.
When data values line up one way or another, whether the slope is positive or negative, the correlation will not be near zero. The graph you want is one that displays no particular trend.
