Question

scatter plot vocabulary assignment
part a: match the terms to their definitions

1. scatter plot a a graph that shows the relationship between two variables using dots
2. data point b a single dot on the scatter plot representing one observation.
3. axis c the horizontal and vertical lines that define the graph area.
4. coordinates d. the pair of numbers (x, y) that show the position of a data point.
5. trend e. the general direction in which the data points seem to go.
6. positive correlation f. as one variable increases, the other also increases.
7. negative correlation g. as one variable increases, the other decreases.
8. no correlation h. no clear pattern or relationship between the variables.
9. cluster i. a group of data points that are close together.
10. outlier j. a data point that is far away from the others and does not fit the pattern.

part b: fill in the blanks

1. a ____ shows the relationship between two variables using dots.
2. a ____ is a dot that represents one observation on the graph.
3. a ____ is a data point that does not fit the pattern of the rest.
4. a ____ correlation means both variables increase together.
5. a ____ is a group of data points that are close together.

Explanation:

1. A scatter plot is a graph showing the relationship between two variables using dots. So, Scatter Plot - A.
2. A data point is a single dot on the scatter - plot representing one observation. So, Data Point - B.
3. Axes are the horizontal and vertical lines that define the graph area. So, Axis - C.
4. Coordinates are the pair of numbers (x, y) that show the position of a data point. So, Coordinates - D.
5. Trend is the general direction in which the data points seem to go. So, Trend - E.
6. Positive correlation means as one variable increases, the other also increases. So, Positive Correlation - G.
7. Negative correlation means as one variable increases, the other decreases. So, Negative Correlation - H.
8. No correlation means no clear pattern or relationship between the variables. So, No Correlation - I.
9. A cluster is a group of data points that are close together. So, Cluster - J.
10. An outlier is a data point that is far away from the others and does not fit the pattern. So, Outlier - F.

For Part B:

1. A scatter plot shows the relationship between two variables using dots.
2. A data point is a dot that represents one observation on the graph.
3. An outlier is a data point that does not fit the pattern of the rest.
4. A positive correlation means both variables increase together.
5. A cluster is a group of data points that are close together.

Answer:

Part A:

1. A. A graph that shows the relationship between two variables using dots
2. B. A single dot on the scatter - plot representing one observation
3. C. The horizontal and vertical lines that define the graph area
4. D. The pair of numbers (x, y) that show the position of a data point
5. E. The general direction in which the data points seem to go
6. G. As one variable increases, the other also increases
7. H. As one variable increases, the other decreases
8. I. No clear pattern or relationship between the variables
9. J. A group of data points that are close together
10. F. A data point that is far away from the others and does not fit the pattern

Part B:

1. scatter plot
2. data point
3. outlier
4. positive
5. cluster
