Across
  1. 7. Describes a relationship where the pattern of points does not follow a straight line but curves or follows another shape; the rate of change between variables varies.
  2. 8. A table that displays the frequency (or counts) of observations for two categorical variables simultaneously, allowing you to examine their relationship and compute conditional or marginal frequencies.
  3. 9. The proportion (or fraction/percentage) of the total observations represented by a particular value or category; calculated as "frequency of the category" /"total number of observations" .
  4. 11. A relationship between two variables where higher values of one variable tend to occur with higher values of the other (points trend upward from left to right on a scatter plot).
  5. 12. The number of times a particular value or category occurs in a dataset.
  6. 13. A straight line drawn through a scatter plot that best represents the trend in the data; it can be drawn by eye or calculated (e.g., with least squares) and used to make predictions.
Down
  1. 1. A situation in which knowing the value of one variable gives little or no information about the value of the other; points on a scatter plot appear randomly scattered with no clear pattern.
  2. 2. A group of points in a scatter plot that are close together, indicating many observations have similar pairs of values in that region.
  3. 3. A relationship between two variables where higher values of one variable tend to occur with lower values of the other (points trend downward from left to right on a scatter plot).
  4. 4. Describes a relationship between two variables that clusters roughly along a straight line; the rate of change between variables is approximately constant.
  5. 5. A graph that displays values for two variables for a set of paired data points; each point’s position shows the pair of values so you can see patterns, clusters, and relationships between the variables.
  6. 6. A data point that lies far from the other points in a scatter plot; it may indicate a measurement error, a rare event, or an important exception.
  7. 10. Data that contain two different variables measured for the same set of subjects or items (for example, height and shoe size); used to study how one variable relates to the other.
