Across
- 1. the distribution of values taken by a statistic in all possible samples of the same sixe from the same proportion
- 3. the pth percentile of a distribution is the value with p% of observations less than or equal to it
- 5. when the individuals in a group differ considerably with respect to the variable of interest
- 8. plot that shows the relationship between two quantetative variables measured on the saem individuals
- 10. when the individuals in a group are quite similar with respect to the variable of interest
- 12. a distribution of quantetative data is ------ to the right if th eright side of the graph is much larger then the left side
- 14. a relationship between two variables in which knowing the value of one variable helps predict the value of the other
- 15. graph that displays the distribution of a quantitative variable by showing each interval of values as bars
- 16. the probability of getting evidence for the alternative hypothesis Ha as storng or stronger than the observed evidence when the null hypothesis Ho is true
- 17. groups of individuals in a population who share chracteristics though tot be associated with the variables being measured in a study
- 19. the design of a statistical study shows ___ if its very likely to over of under estimate the value you want
- 22. a graph of quantitative data with two clear peaks
- 23. value in disribution having the greatest frequency
- 24. individual value that falls outside the overall pattern of a distribution
- 27. a treatment that has no active ingredient but is otherwise like other treatments
- 29. the same on both sides
- 30. variable that tales number values that are quanteties - counts of measurements
- 31. a measure of variablilty equal to distance between the minimum and maximim value of a distribution
- 32. using a chance process to determine which members of a population are chosen of a random process
- 33. the midpoint of a distribution
- 34. describes the fact that some subjects in an experiment will respond favorably to any treatment, even an inactive one
- 36. difference between an actual value of the response variable and the value predicted by the regression line
- 37. in a statistical study the entire group of individuals we want information about
- 38. describes how far, at most we expect the estimate to vary from the population value
Down
- 2. specific value of a point estimator from a sample
- 4. a graph that displays the distribution of a quantitative variable by plotting each data value as a dot above its location on a number line
- 6. a group of individuals in the population that are located near eachother
- 7. claim we have evidence against in a signifigance test
- 9. a modified segmented bar graph in which the width of each rectangle is proportional to the number of individuals in a corresponding category
- 10. the claim that we are trying to find evidence for in a significance test
- 11. the avergae of all the individual data values in a distrubution of quantetative data.
- 13. subset of individuals in the population from which we collect data
- 18. a statistical measure that isnt sensitive to extreme values
- 20. an object described by a set of data
- 21. in the regression equation the ------ is the amount by which the predicted value of y changes when x increases by unit 1
- 25. variable that takes numerical values that describe the outcomes of a random process
- 26. a number that describes some chracteritics of a population
- 27. a number between 1-0 that describes the proportion of times an outcome of a random process would occur in a very long series of trials
- 28. tells what values a variable takes and how often it takes these values
- 35. explanatory variable in an experiment that is manipulated and may cause a change in the response variable
