For this question, you are required to find the standard deviation for a set of data. The answer alone will not achieve full marks. There are many tools available to calculate the standard deviation. Here you are required to use several of the tools and show your working out to earn the marks. The data is the test results of 21 students who sat a mathematics quiz worth 100 marks. Results: 60, 47, 17, 43, 30, 90, 77, 61, 54,...

3. Use the data table below to answer the following questions: (a) The least absolute deviation line for the data in the table is y - 1.5x +17. What is the sum of the absolute deviations? (b) Find the median-median regression line for the data in the table. (c) Using the equations for the least absolute deviation line and the median-median regression line determine which model does a better job of predicting the y-value for x 11.* 21 20 38...
