Math Project   Due January 8,2018

Design and conduct a survey.

Survey must include at least 5 collection criteria (including "other")

Collect at least 100 pieces of data. You will be expected to submit your tally chart as part of your assignment.

Organize the data into a google spreadsheet and have the application generate an appropriate graph.

Grade 5's

Calculate the mean, range, and mode of your data.  Write a short paragraph which makes an inference from the data.  A second paragraph telling why the graph you have chosen to present your data is the appropriate choice.

 

Grade 6's

Calculate the mean, range, median and mode of your data.  Write a short paragraph which makes an inference from the data. A second paragraph telling why the graph you have chosen to present your data is the appropriate choice.

 

Items to submit

-tally of collected data

-google sheet with graph

-a calculations page which may be included on your google sheet

-two paragraphs (which my be imbedded in your google sheet)

                -telling the inference(s) that you can draw from you data

                -justifying the graph choice you have made 



Helpful definitions

mean:  take your data, add it up and then divide by the number of data items (example: if your data is 4,6,10,20   the mean is (4+6+10+20) ÷ 4= 10)

range: take the least value and subtract it from the largest value (example: if your data is 4,6,10,20   the range is 20-4 = 16)

median : take your data and line it up from smallest to largest, locate the middle value.  (example: if your data is 4,6,10,20,25  the median is 10 because it is situated in the middle.  Note: if your data is 4,6,10,20 you must calculate the mean of the middle two numbers because the number of data is even, so the median is (6+10) ÷ 2 = 8)

mode: take your data and line it up from smallest to largest, identify the data that occurs most often (example: if your data is 4,6,10,10, 20,25  the mode is 10 because it  occurs the most. Note: if your data is 4,6,10,20 there is no mode.  If your data is 4,6,10,10, 20,20 the mode is 10 and 20)
