The data points in the scatter plot move up the y-axis as the x-axis decreases; thus the data points show a negative association. Also, the data points do not curve, or go up and down, but gradually decreased; thus the scatter plot shows a linear association. We could even draw a "best fit" line:

Which of the following represents a positive association in a scatterplot?
Which of the following represents a positive association in a scatterplot?
A positive association is defined as a scatterplot on which the best fit line has a positive slope.
This pattern is identified because on the graph, looking from left to right, the vast majority of the points goes up.
This can also be described by saying, "as

When creating a scatterplot, data is collected. This data is formulated into ordered pairs. Each of these ordered pairs, which are later graphed, represent one person's data. Thus, this particular piece of data would represent one man's height of 
inches and that same man's shoe size of

Which of the following would most likely represent an outlier on a scatterplot which relates height (in inches) to shoe size for men?
Which of the following would most likely represent an outlier on a scatterplot which relates height (in inches) to shoe size for men?
An outlier is defined as a point that does not fit within the general pattern of the data. Thus, we are looking for a height that is not within the normal range for an adult male, and shoe size which is outside of the range for an adult male. Typically, an adult male would be between 65 and 77 inches tall (5 feet 5 inches and 6 feet 5 inches). Typically, an adult male's shoe size would be around a 10. Thus, the outlier would have height and shoe size drastically different from these,

What type of correlation does this data have?
What type of correlation does this data have?
It has a positive correlation because the points all trend upward. In other words, as the independent variable on the x-axis increases, the dependent variable on the y-axis also increases. Therefore, the line of best fit that is drawn through the data represents a positive line as it has a positive slope. This verifies that our data has a positive correlation.

I. The price of a higher quality snack tends to be higher.
II. Points below the line represent snacks whose price is higher than their quality.
III. Points above the line represent snacks whose quality is higher than their price.

I. The price of a higher quality snack tends to be higher.
II. Points below the line represent snacks whose price is higher than their quality.
III. Points above the line represent snacks whose quality is higher than their price.
I. is a true statement about the scatter plot: as quality increases, price tends to increase.
II. is not true - the points under the line have a relatively low price compared to their quality.
III. is also not true - the points above the line have relatively low quality compared to their price.

The scatter plot provided displays a group of students' test scores versus the length of time the students spent studying for a test. Based on plot, which of the following patterns does the relationship between number of hours spent studying and the corresponding test score represent?
The scatter plot provided displays a group of students' test scores versus the length of time the students spent studying for a test. Based on plot, which of the following patterns does the relationship between number of hours spent studying and the corresponding test score represent?
In the provided scatter plot, we can pick out data points and organize them from least to greatest, based on hours spent studying:
Based on the results, we can see that as the number of hours spent studying increased, the test grade also increased; thus, a positive association, a higher number of hours spent studying correlated to a higher test score.

To answer this question correctly, we need to recall what "outlier" means. An outlier is a value that is much smaller or larger than the rest of the values in a set of data. Also, a data point that does follow the same pattern as the rest of the set could be described as an outlier. In this case, if we had a student that studied 
hours, but received a test score of 
that data point would be considered an outlier because it doesn't follow the same pattern as the rest of the set. However, there are no data points in this set that don't follow the pattern; thus, there are no outliers in this set.
