Line Graph Project By Harleen Suri, Eliza Neights, Carina Tse

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

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

How We Made the Graph Draw and label a x- axis and y- axis
Create a scale on each axis Plot your data points Connect each point with line segments Give your graph a title

Quiz Question A TV company wants to schedule commercials during the day kids watch the most amount of TV. Mrs. Ellwood’s 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.

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%

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

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