### Transcript of Graphed Grant Results

• 1. Mrs. Johnstons 5 thGrade Math Class Lincoln Elementary Mount Vernon, WA USA

2. The Process:

• Our class brainstormed both categorical and numerical survey questions.
• We poled our classmates and graphed the results in teams of two students.
• We submitted 3-5 good questions to our classmates.
• Through classdiscussions we evaluated the questions on whether or not the data could be graphed clearly or not.
• Then we voted.
• The following questions were our top three questions that were placed on an onZoomerangwebsite for any and all to take.

3. We wanted to know:

• What is your favorite day of the week?
• What is your favorite season of the year?
• How many siblings do you have?

4. We had a total of 134 responses from studentsall over the world. How Cool is that? 5. Number of Siblings Data: Number of Siblings Number of Students Percent of Students with this # of Siblings 0 3 2% 1 52 40% 2 38 29% 3 22 17% 4 9 7% 5 2 2% 6 1 1% 7 1 1% 8 1 1% 9 1 1% Total 131 100% 6. Graphed Results 7. Averages of Number of Siblingsin your Family

• Numerical Datahas averages of mean, median, and mode.(Numerical Data is information collected in number form.)
• Modefor most common number of siblings is1sibling. So, this tells us that most students were from families with 2 children. (40%)
• Median(middle of the data) 2 siblings: This would mean that each family would have a total of 3 children. This Average is not the most common but the middle of the data. (29% of the students had this as their choice.)
• Mean 132students 10 sibling categories (See next Slide)

8. Mean Results:

• The totals were 270 siblings and 130 respondents.
• Added 3 + 52 + 38 + 22 + 9 + 2 + 1 +1 + 1 + 1 to get the total number of respondents as 130 respondents.
• To get the total number of siblings add 52 + 76 + 66 + 36 + 10 + 6 + 7+ 8 + 9 to get a total of 270siblings.
• 270/130 = a mean of 2.0769 per respondent.
• Thank you Lisa Condran for your assistance in this Mean Data.
