Across
- 4. graphical representation of the distribution of the data, it has the characteristic of having its bars sticking next to each other
- 6. difference between an observed and predicted value
- 7. number expressing the likelihood that the specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences
- 9. predicting the unknown future
- 14. common display for data, can tell patterns, trends, relationships, and even outliers.
- 17. by summing items in a set and dividing by the number of the terms
- 18. difference between the quartiles tells us how much territory the middle half of the data covers
- 19. sum of multiplying each possible value by the probability that it occurs
- 21. middle number of a set of numbers arranged in numerical order
Down
- 1. measure of position that takes into account both the center and the dispersion of the distribution
- 2. that describes the number of the successes in a specified number of trials
- 3. expected value of those squared deviations
- 5. square root of the variance
- 8. that only have 2 outcomes, the probability of each trials is the same, and trials are independent
- 10. value of the random phenomenon
- 11. visual representation of dispersion that shows the smallest, largest value, the median, and both Q1 and Q3
- 12. that have nothing in common
- 13. arrangement of values of a variable showing their observed or theoretical frequency of occurrence
- 15. as the difference between the maximum and the minimum
- 16. is far from the mean of the x-values
- 20. occasion upon which we observe a random phenomenon
