DSST Intro To Statistics

Subjects : dsst, statistics
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. To divide the population into 2 or more non-overlapping subsets called strata






2. An individual data value which lies far (above or below) from most or all of the other data values within a distribution






3. Statistics






4. Is the process of selecting a portion - or sample - of the entire population






5. Occur when one does not affect the probability of the occurrence of the other.






6. Test use normalcdf(ZTS -999)






7. A method in which each combination of people has an equal chance of being selected- the sample is representative of the population and is independent






8. The pattern of variation of data. The distribution may be described as symmetrical - positively skewed - or negatively skewed






9. Information about individuals in a population






10. A descriptive tool used to visually describe the characteristics and relationships of collections of data quickly and attractively






11. For a left tailed test use normalcdf(-999 - ZTS)






12. Create a sample by using data from population members that are readily available






13. The variable value can be represented as isolated points on a number line






14. To calculate the percentile take the number of values less than x - divide by total number of values and times by 100.






15. Sample size or number of trials






16. A method of data collection in which the objects of study are observed in their natural settings and the variables are recorded






17. Graph involving pictures of objects in which the size of the object in which the size of the object in the picture represents the relative size of the quantity being represented by the object.






18. Is a number that describes a characteristic of a population






19. Double the answer from step 1 or step 2 (on whichever side your test statistics falls).






20. A numerical quantity measuring some aspect of the population






21. _______________ of a numerical variable represents the data values of the variable from the lowest to the highest value along with the number of times each data value occurs






22. Capital sigma; summation






23. Range - standard deviation and variance.






24. Level of measurement- Involves data that may be arranged in some order - but differences between data values either cannot be determined or are meaningless. (Example) Questions on a survey are scored with integers 1 thru 5 with 1 representing strong






25. Occur when one of them affects the probability of the other.






26. Determine the location of the middle value of all the data values






27. Alternative hypothesis






28. Always use a equal symbol






29. Population proportion






30. A method of data collection where the researcher selects a sample from the population and measures the variable of interest






31. Is a number that describes a characteristic of a sample

32. Sum of the values






33. Type of bar graph that shows frequency distributions






34. When the distribution of the data values tend to be concentrated toward one end of the display or tail of the distribution - while the data values in the other tail are spread out through extreme values resulting in a longer tail






35. Sample variance






36. Population is organized into groups (i.e - neighborhoods/departments) - and sampling unit is selected by a simple random sample






37. Middle value of a set of data values after they've been arranged in numerical order - 1. First arrange data values in numerical order 2. For odd # of data values - the median is the middle data value 3. For even # of data values - the median is the m






38. (largest data value) - (smallest data value)






39. Sample proportion






40. Population variance






41. Is denoted by 'N' - is the number of data values in the population






42. Is the entire collection of all individuals or objects of interest






43. Sample mean






44. Data values that are either much larger or much smaller than the general body of data- they should be included in an analysis unless they are the result of human or other error






45. Has the same shape and horizontal scale as a histogram - but the vertical scale is marked with relative frequencies instead of actual frequencies






46. Complement of p






47. A method in which you randomly choose one number from 'l' to 'k' and continue to select the kth element






48. Variable where the value is a number that results from a measurement process - also called numerical data






49. One extreme value can affect it dramatically.






50. Involves the procedures associated with the data collection process - the summarizing and interpretation of data - and the drawing of inferences or conclusions based on the analysis of the data
