<p>Mathematical Meanings- Probability Literacy Task</p><p>Firstly, you need to make sure you are searching the Internet correctly. The new unit is probability. Hence you need to search for “probability definition”. As you have discovered in your previous ‘card task’, words can be spelt the same but have different meanings. This is called a homonym. Hence it is important that we know how to search the web and which resources are useful to our purpose.</p><p>You need to search using either of the following resources: http://www.amathsdictionaryforkids.com/ http://www.mathsisfun.com/definitions/letter-c.html http://www.mathwords.com/c.htm</p><p>Importantly, you do not write a definition down that you do not understand! This makes the exercise pointless to your learning. And, that’s not great news for us. You may need to read 2 or 3 different definitions before you are confident to write one down. Using the word list on page 2, complete the two tasks below. An example has been provided to you using words from the previous unit in statistics.</p><p>Task 1: 4 words I know Use word in a sentence to show meaning Median If I ordered my class of 41 students from shortest to tallest, the median person would be number 21 because they are exactly in the middle. </p><p>Task 2: 6 words I don’t know Mathematical meaning Use word in a sentence to show meaning Mean The average of the numbers, If I wanted to calculate my a calculated ‘central’ value mean score on the beep test for a data set. over 3 trials I would need to add up the results, and divide by 3. LEVEL 4-5  Event  Decimal  Outcome  Fraction  Likely  Experiment  Represent  Equally  Probability  Chance  Unlikely  Impossible</p><p>LEVEL 6-7  Percentage  Sample space  Conduct  Favourable  Observed  Trial  Expected  Assign  Frequency  Determine</p><p>LEVEL 8-10  Complement (of an event)  Array  Two-step experiment  Replacement  Exclusive  Tree diagram  Inclusive  Relative frequency  Venn diagrams  Independent (events)  Conditional probability  Estimate  Data  Represent  “at least”  “and”  “or”</p>
