Introductory Social Statistics IMPORTANT INSTRUCTIONS: |show statistical formula used, process of computation, and provide meaningful interpretations of results in full sentences. Any table have to be labeled appropriately (c.g., title and column). Columns in a table should be meaningfully labeled in concise words and with statistical symbols. • Calculations could be rounded up to nearest two decimal points • Assessment of answers will include producing a neat work, clear interpretation or reasoning, and statistical correctness. Questions A The following are the test scores of students in a 200-level statistics course: 66 89 47 63 40 51 62 80 60 97 48 64 67 97 60 67 81 64 74 38 69 50 59 80 57 33 47 72 68 91 74 47 73 50 52 43 54 98 54 63 79 33 51 54 60 44 82 43 32 48 46 57 47 92 72 87 71 79 84 41 40 58 44 61 38 92 71 41 83 84 1) Draw a frequency distribution table of ungrouped data and provide necessary columns and rows of statistical information and symbols (c.g., frequencies, relative frequencies and percent, cumulative frequencies and percent, total frequencies or N, and total scores IEXI()]-| 2) What percent of students received the highest score and the lowest score? 3) What percent of students received the most common score? 4) What score did the students receive on average? Show statistical formula and process of calculation. 5) What score did almost half of the students receive? Show statistical formula and process of calculation. 6) Draw a grouped frequency distribution table providing necessary statistical information (c.g., mid-points, frequencies, relative frequencies and percent, cumulative frequencies and percent, total frequencies or N, and total scores (EMi()]. Explain how you would make a decision to determine the class size or class limits. | 7) Calculate the mean from the grouped data. Show statistical formula and process of calculation. How different is this mean from the average calculated from the ungrouped data? | 8) If you were asked to draw a chart or graph, which one would you to choose from histogram, pie, or line chart to visually show the trends in the test scores? Why?|
