1.2+Targeting+an+Audience

MT 26.01.09 Block E How to find a percent: First divide the partial number by the whole and then times the number by 100; this will give you your percent. Example: 8 students prefer radio out of 21 students what is the percentage? step 1: 8/21=0.38095238 step 2: 0.38095238 round to o.38 step 3:0.38x100=38=38% Above is the working out for follow-up 1a) __Problem 1.2__** A) //**Read the statements below about how Neilson students prefer to spend their evenings. Tell whether each statement accurately reports the result of the survey.**// 1)**6 0ut of 10 students prefer television to radio**-This statement is accurate because 60 out of 100 students prefer television and if you divide the data by 10 you get 6 out of 10. 2)**Students prefer radio to television by a ratio of 4 to 6** - This statement is accurate because 40 to 60 students prefer radio and if you divide the data by 10 you get 4 to 6. 3) **Students who prefer television outnumber those who prefer radio by 20**- This is an accurate statement because 40 -60= 20; this calculation shows the difference is 20 and because more people prefer television 20 more people prefer television than radio. 4) **Students who prefer television outnumber those who prefer radio by a ratio of 3 to 2**- This is accurate because the original results have a ratio of 60 to 40 and if you divide this data by 20 you get 3 to 2. 5)**The number of students who prefer watching television is 1.5 times the number who prefer listening to radio**- This statement is accurate because 40 times 1.5 equals 60. 6)**40% of the students prefer radio to television**-This statement is accurate because 40 students prefer radio out of 100 and 40 divided by 100 = 0.04 and x by 100 equals 40%. 7) **3/5 of the students prefer television to radio**- This is accurate because 60/100 students prefer television to radio and if you divide 60/100 by20 you get 3/5. B)//**If you were writing a paper to convince local merchants that they would reach more students by advertising on radio than on television, which statement from above would you use? Why?**// I would use statement 6 because it talks mainly about radio and the percentage is quite high and catchy. C) **//Imagine that you are the advertising director for a television station in the town where Neilson is located. You have been asked to prepare a report for a meeting between your ad department and a large local skateboard manufacturer. Which accurate statement from above would you use to try to convince the manufacturer to advertise on your station? Why?//** I would choose statement 1 because it clearly shows more than half of the students prefer television and it is simple and easy to remember. __ Problem 1.2 Follow-Up __ **Conduct a quick survey in your class to find out how many students prefer watching television t in the evening and how many prefer listening to the radio (we used spending time on the internet instead in our class survey). Record the results in a table.**
 * __Big Idea:__** many important practical and mathematical applications involve comparing quantities of one kind or another;it is important to know which method to use and how we should use them.
 * __Essential question:__** What methods are there for comparing things?
 * __Notes from class:__** Seeing how much times smaller or bigger an object is, is a way to compare results. Percentages and fractions are also a way.
 * __1.2 Targeting and audience__
 * A survey of a 100 students at Neilson middle school found that 60 students prefer watching television in the evening and 40 prefer listening to radio.**
 * || Television || Internet ||
 * Girls || 7 || 3 ||
 * Boys || 1 || 10 ||
 * Total || 8 || 13 ||

1)  **// For each statement in part A on page 7, write a similar statement about your class data. //**  a)   13 out of 21 students prefer the internet to television. b)  Students prefer television to internet by a ratio of 8 to 13.   c)   Students who prefer internet outnumber those who prefer television by 5. d)  Students who prefer internet outnumber those who prefer television by a ratio of 8 to 13.   e)   The number of students who prefer spending time on the internet is 1.65 times the number who prefer watching television. f)  38%   of the students prefer television to internet.    g)   8/13 of the students prefer internet to television. 2)  **//In what ways is your class data similar to the Neilson data? In what ways is your data different?//**  First of all our data is very different because we used television and internet instead of television and radio and we had less people in our survey. What is also different is that our data includes less people and the number of people add up to an odd number. The only similarity is that we also took a survey to know what students prefer. 3) **//You may have heard people talk about an interest group __manipulating__ data to promote their cause. This doesn't mean they used incorrect data, but that they made careful decisions about which data to use and how to represent the data to support their cause. How could you manipulate your class data to persuade local merchants to advertise on the radio(television according to class data) rather then on the television(internet according to class data)?//** I would manipulate the data by using the statement :more then 37% of students prefer television to internet. This statement is a good way to persuade merchants because you don't let them no the exact data but you tell them that their is at least 37% more students that prefer television.
