Line Graph Project FOR CLASS 5 301 What

Line Graph Project FOR CLASS 5 -301

What is a Line Graph? �Graph used to represent data with an independent and dependent variable when showing changes over time �Data is plotted on the graph and connected with lines

When is it Used? �When you are showing changes over time

Real World Example �The graph shows the temperature (°F) of New York City over 6 days �Can easily see trend of data �Could be used by meteorologists

What Type of Data Do You Need? � Set of data- Can be a single or multiple or single set �Need key if using multiple sets of data

Data Collected Average Time Spent Watching TV in Mrs. Davis’ Class Time (minutes) Monday 37 Tuesday 40 Wednesday 39 Thursday 43 Friday 52 Saturday 83 Sunday 80

Average Time Spent Watching TV in Mrs. Davis’ Class 90 83 80 80 Time (min. ) 70 60 52 50 40 37 40 39 43 30 20 10 0 Monday Tuesday Wednesday Thursday Friday Days Spent Watching TV Saturday Sunday

Quiz Question A TV company wants to schedule commercials during the day kids watch the most amount of TV. Mrs. Davis’ class was selected to complete a survey based on how much TV they watch. Find the largest increase in time TV was watched. Then, find the percent of increase of time TV was watched.

Average Time Spent Watching TV in Mrs. Davis’ Class 90 83 80 80 70 Time (min. ) 60 52 50 40 37 40 39 43 30 20 10 0 Monday Tuesday Wednesday Thursday Friday Days Spent Watching TV Saturday Sunday

How to Solve � Find the largest increase in the graph. � From Friday to Saturday, the increase in time was greatest � Then find percent of increase to the nearest tenth Difference Original = 83 -52 52 ≈ 59. 6%

Advantages of Line Graphs �Can visually see the trend of the data �Can see how data increases/decreases �Can compare two sets of data �Use a line graph with multiple sets of data

Disadvantages of Line Graphs �Hard to see the specific data points when the scale is large �Sometimes the scale can change the appearance of the data

CAN YOU SHOW A CHANGE IN KIDS’ SLEEP PATTERNS? �Think about it. We read about the importance of getting enough sleep and causes that may impact kids from getting enough sleep.

CAN YOU CREATE A LINE GRAPH USING THIS DATA? :

USE THE “HOW WE CREATE A LINE GRAPH” CHART OR: �GO TO: http: //nces. ed. gov/nceskids/graphing/classic/

HOW ABOUT CREATING YOUR OWN SURVEY AND LINE GRAPH? a. Identify a Question or Problem b. Collect Data or Evidence c. Create a line graph to display data d. Analyze Data e. Draw Conclusions f. Share Findings

CONSIDER: �Consider questions that relate to your topic: �What do I notice? �What do I wonder? �What interests me? �Why does. . . happen? �What causes. . . ? �Can my question be answered by collecting the right data?

HERE’S ONE TO TRY IF YOU GET STUCK FOR YOUR OWN IDEA:

REMEMBER: �YOU WILL BE FOCUSING ON A TREND OR CHANGE OVER TIME!
