| Card: 4 / 36 |
Fill in the blank: The variable plotted on the x-axis of a scatterplot is known as the ___ variable. | Card: 5 / 36 |
An outlier is a significant data point.
| Card: 8 / 36 |
True or False: A scatterplot with a strong association will have points that are widely dispersed and do not follow a clear pattern. | Card: 9 / 36 |
False. A scatterplot with a strong association will have points that closely follow a recognizable pattern, often resembling a line or curve. | Card: 10 / 36 |
Riddle: I can show you the relationship between two things, but I am not a person. I can tell you if they go up together or if one goes down while the other rises. What am I? | Card: 11 / 36 |

Fill in the blank: In a scatterplot, the variable plotted on the x-axis is called the ___ variable. | Card: 19 / 36 |
Explain the difference between interpolation and extrapolation when making predictions from a scatterplot. | Card: 21 / 36 |
Interpolation is within data range.
| Card: 22 / 36 |
True or False: A scatterplot can show a positive association between two variables if, as one variable increases, the other variable also decreases. | Card: 23 / 36 |
False. A positive association means that as one variable increases, the other variable also tends to increase. | Card: 24 / 36 |
Riddle: I can show you patterns and trends, but I'm not a story. I plot points to reveal connections between two variables. What am I? | Card: 25 / 36 |
In a scatterplot showing the relationship between hours spent studying and test scores, what does a strong positive association indicate? | Card: 27 / 36 |
A strong positive association indicates that as the number of hours spent studying increases, the test scores tend to increase as well. | Card: 28 / 36 |
Identify the term used to describe a data point that does not fit the overall pattern of a scatterplot. | Card: 29 / 36 |
Fill in the blank: A scatterplot with points that show no clear upward or downward trend is said to have ___ association. | Card: 31 / 36 |
Clusters indicate data subgroups.
| Card: 34 / 36 |
Explain why it is important to consider other variables when interpreting the results of a scatterplot. | Card: 35 / 36 |
Consider other variables in analysis.
