I am really struggling with this, help is appreciated. Thanks! :)
11. A team of scientists studied the behaviors of rabbits. They looked at two kinds of behaviors: exploratory and locomotor. Some exploratory behaviors were sitting up, looking around, and sniffing. Some locomotor behaviors were running, jumping, and trying to escape. They also noted when rabbits had positive interactions with other rabbits. For example, a positive interaction could be nuzzling or grooming other rabbits.
The scientists then analyzed the data. They compared the number of each type of behavior with the number of positive interactions the rabbits had. The scientists were looking for a possible connection between behaviors and positive interactions. The scatterplots below show their data.
a. Describe the pattern shown in each scatterplot. (2 points)
b. What is a line of best fit, and how does it help you interpret the data represented in a graph? (2 points)
c. Based on the data in scatterplot B, how do you predict a rabbit's positive interactions would change if its locomotor behaviors decreased? (1 point)
12. The correlation coefficient for scatterplot A, comparing positive interactions and exploratory behavior, is r = 0.59. The correlation coefficient for scatterplot B, comparing positive interactions and locomotor behavior, is r = 0.6.
a. Use each correlation coefficient to describe the strength of the relationship shown in each scatterplot. (2 points)
b. The scientists also calculated the correlation coefficient for the relationship between exploratory behaviors and locomotor behaviors. They found a correlation coefficient of r = 0.64. Which of the three relationships is the strongest? Explain. (1 point)
c. Do the data in the scatterplots indicate causality? Explain. (2 points)
