  1. Chapter 3; Data and Statistics. Period 3 Math

  2. Selection of content. We chose chapter 3; Data and Statistics, because, we’re good at gathering data and stuff like that. Data and Statistics can be fun too.

  3. Vocabulary – Mean. • The mean is the average of the numbers: a calculated "central" value of a set of numbers. • To calculate: Just add up all the numbers, then divide by how many numbers there are. Example: what is the mean of 2, 7 and 9? Add the numbers: 2 + 7 + 9 = 18 Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6 So the Mean is 6

  4. Vocabulary – Median. • The middle number (in a sorted list of numbers). • To find the Median, place the numbers you are given in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. Put them in order: {10, 11, 13, 15, 16, 23, 26} The middle number is 15, so the median is 15. (If there are two middle numbers, you average them.)

  5. Vocabulary – Mode. • The number which appears most often in a set of numbers. Example: in {6, 3, 9, 6, 6, 5, 9, 3} the Mode is 6 (it occurs most often).

  6. Vocabulary – Range. • The difference between the lowest and highest values. • Range can also mean all the output values of a function. Example; In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9, so the range is 9-3 = 6.

  7. Real World Connection. Data- Real World Data is used in health research to describe data generated in day to day situations rather than controlled clinical trials. In clinical trials patients have to be carefully selected to ensure that the results are not due to some other condition or treatment the patient is receiving. This provides valuable data regarding the safety and efficacy of the medicine but doesn't tell us how patients will respond to the medicine in real life when they have other conditions and are taken other medicines. To understand what happens in these situations we can collect patient records from GPs, hospitals and other locations where the personal details of the patient have been removed or anonymised. By using computers to analyze the records we can obtain a great amount of information about medicines, treatments and results. This is Real World Evidence from Real World Data. Statistics- Statistics is the art of gathering, analyzing and making conclusions from data. Most of the significant development in the theory of statistics didn't occur until the late nineteenth century and early twentieth centuries. Francis Galton and Karl Pearson began the study of making inferences from data with their work in the late nineteenth century. They advanced statistics by inventing with their followers standard deviation, correlation, and correlation, and coefficient.
