Statistics and data crossword vocabulary pack

Teacher key

1. DATASET · 7 letters · noun · introductory
   Organized collection of values used for analysis

   Hint: Think of the numbers or observations gathered before making a graph.
   Why it fits: DATASET fits because statistics begins with a structured group of observations that can be sorted, graphed, summarized, or compared.

2. SAMPLE · 6 letters · noun · introductory
   Smaller group studied to learn about a larger group

   Hint: Pollsters use only part of the whole population when asking questions.
   Why it fits: SAMPLE fits because researchers often measure part of a population and use that evidence to make careful conclusions about the whole.

3. CENSUS · 6 letters · noun · introductory
   Count or study that includes every member of a population

   Hint: Governments use this kind of count to learn about all residents.
   Why it fits: CENSUS fits because it describes collecting information from the entire population being studied instead of from only selected members.

4. SURVEY · 6 letters · noun · introductory
   Question-based method for collecting responses

   Hint: It might ask classmates about opinions, habits, or preferences.
   Why it fits: SURVEY fits because it names an organized way to collect data from people by asking the same or related questions.

5. OUTLIER · 7 letters · noun · intermediate
   Value that sits far away from the rest of a data group

   Hint: On a dot plot, look for the point separated from the cluster.
   Why it fits: OUTLIER fits because one unusually high or low value can affect summaries such as the mean and may need special attention.

6. RANGE · 5 letters · noun · introductory
   Difference between the greatest and least values

   Hint: Subtract the smallest value from the largest value.
   Why it fits: RANGE fits because it gives a quick measure of how far a data set stretches from its lowest value to its highest value.

7. FREQUENCY · 9 letters · noun · introductory
   Count of how many times a value or category appears

   Hint: A tally mark table records this for each category.
   Why it fits: FREQUENCY fits because a table or bar graph often starts by counting how often each response or value occurs.

8. HISTOGRAM · 9 letters · noun · intermediate
   Bar graph that groups numerical data into intervals

   Hint: Its bars usually touch because each bar covers a number bin.
   Why it fits: HISTOGRAM fits because it shows how many data values fall within each numerical interval, making the distribution easier to see.

9. SCATTERPLOT · 11 letters · noun · intermediate
   Dot graph comparing two numerical variables

   Hint: Each point has an x-value and a y-value.
   Why it fits: SCATTERPLOT fits because it lets students inspect whether paired measurements move together, move oppositely, or show little pattern.

10. CORRELATION · 11 letters · noun · intermediate
    Pattern showing how two variables tend to change together

    Hint: It can be positive, negative, or close to zero.
    Why it fits: CORRELATION fits because it names the strength and direction of an association seen in paired data, without by itself proving cause.

11. CAUSATION · 9 letters · noun · advanced
    Relationship in which one factor directly produces a change in another

    Hint: This is stronger than just seeing two patterns move together.
    Why it fits: CAUSATION fits because statistics classes distinguish direct influence from an association that may be explained by another variable.

12. TREND · 5 letters · noun · introductory
    General pattern of increase, decrease, or steady change

    Hint: Look at the overall direction rather than one single point.
    Why it fits: TREND fits because students use this term when describing the broad direction shown by data, not every small fluctuation.

13. DISTRIBUTION · 12 letters · noun · intermediate
    Overall shape of how data values are spread

    Hint: It can be centered, skewed, clustered, or widely spread out.
    Why it fits: DISTRIBUTION fits because it describes the full pattern of data, including center, spread, clusters, gaps, and unusual values.

14. VARIANCE · 8 letters · noun · advanced
    Average squared distance from the mean

    Hint: Large values mean the numbers are more spread out from the center.
    Why it fits: VARIANCE fits because it quantifies how far data values typically lie from the mean after each distance is squared.

15. QUARTILE · 8 letters · noun · intermediate
    Cut point that helps divide ordered data into four parts

    Hint: Box plots use first and third versions of this marker.
    Why it fits: QUARTILE fits because these cut points help describe the middle and spread of ordered data, especially in box plots.

16. PERCENTILE · 10 letters · noun · advanced
    Rank showing the percent of values at or below a score

    Hint: A score at 80 on this scale is above most scores in the group.
    Why it fits: PERCENTILE fits because it locates a value within an ordered data set by comparing it with the rest of the values.

17. INTERVAL · 8 letters · noun · intermediate
    Span between two values used to group data

    Hint: A graph might collect ages 10 through 14 in one bin.
    Why it fits: INTERVAL fits because grouped displays often count how many observations fall within each chosen span of values.

18. RANDOMNESS · 10 letters · noun · intermediate
    Unpredictable variation caused by chance

    Hint: A fair die roll shows this because the next result is uncertain.
    Why it fits: RANDOMNESS fits because probability models account for variation that cannot be predicted exactly in advance.

19. ESTIMATE · 8 letters · noun · introductory
    Reasoned approximation based on available information

    Hint: It is close enough for a purpose, even if it is not exact.
    Why it fits: ESTIMATE fits because students use data and context to choose a reasonable approximate value when exact measurement is unavailable.

20. PARAMETER · 9 letters · noun · advanced
    Numerical fact about an entire population

    Hint: A statistic from a subset may be used to approximate it.
    Why it fits: PARAMETER fits because it names the population value that researchers often try to infer from collected data.
