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. Always use a equal symbol






2. Sample proportion






3. Standard scores and percentile






4. Collection of information from the whole population






5. Is a sample that has the pertinent characteristics of the population in the same proportion - as they are included in that population






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






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






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






9. Members of the population select themselves by volunteering






10. Complement of p






11. When the distribution of the data values greater than the center of the display - and the data values less than the center of the display are mirror images of each other






12. Statistics






13. One extreme value can affect it dramatically.






14. Uses numerical and or visual techniques to summarize or describe the data in a clear effective manner






15. 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.






16. Is the portion of the population that is selected for study






17. A sample which is selected in such a manner - that each data value of the population has a non-zero probability of being selected for the sample






18. A quantity calculated from data gathered from a sample- usually used to estimate a population parameter






19. Level of measurement- Is like the ordinal level - with the additional property that we can determine meaningful amounts of differences between data. However - there is no inherent (natural) zero starting point (where none of the quantity is present).






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






21. Mu; population mean






22. Level of measurement- involves data that consist of names - labels and categories only. The data cannot be arranged in an ordering scheme (such as low to high). (Example) Nationalities of survey respondents






23. Before they are arranged or analyzed - information or observations are called________.






24. Population proportion






25. A flaw in the sampling procedure that makes it more likely that the sample will NOT be representative of population






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






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






28. The important aspects of the data are called?






29. _______________ are numerical measurements that can assume any value between two numbers






30. Probability of event A






31. Is the process of using SAMPLE INFORMATION to draw inferences or conclusions about the POPULATION






32. Sum of the values






33. 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






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






35. Sample size or number of trials






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

37. To find the range subtract the lowest value by the highest value.






38. Is a sample containing similar characteristics of the population






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






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






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






42. Null hypothesis






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






44. A method of experimentation in which you can control as many variables as possible in order to isolate the effects of a response variable






45. Parameter






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






47. A survey that includes every item or individual of the population






48. Collection of information from a sample






49. A numerical quantity measuring some aspect of the population






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