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 7) Calculate the mcan 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? |

Matrices

‘Matrices’ is the plural form of the word matrix, and it is basically a spreadsheet in the form of a box. In mathematics, various functions can be carried out with matrices. Generally, a matrix comes in the shape of a square or rectangle. The elements are distributed horizontally in the form of rows, and vertically in the form of columns.
