Lesson 3: Line plots

A line plot is a graph that displays data using a number line. To create a line plot, ​first create a number line that includes all the values in the data set. Next, place an X (or dot) above each data value on the number line. If a value occurs more than once in a data set, place ​an Xs​ over that number for each time it occurs.

• When he says he will create buckets in the beginning what dose he mean
• 'Buckets' refer to the unit he's using to measure a number on a graph. So if I had 40 suckers and that's counted on a graph my bucket would go to 40.
• Can you use strategies other than number lines to do them?
• Age is a number, so it is better to use number line (age increases after a year, number line is increasing too). However, there is many other ways to visualize it, like graph bars or just table which was used in the video to construct the line plot
• When is it better to use bargraph, line plots, pictogram, or histogram?
• Bar Graphs-Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger. (https://nces.ed.gov/nceskids/help/user_guide/graph/whentouse.asp)

Line plots-Line plots help organize information. Using line plots can help us easily analyze the range and the mode of a set of data (http://studyjams.scholastic.com) USE IF YOU ARE DETERMINING MODE, MEDIAN, MEAN, RANGE

Pictograph: A pictograph uses picture symbols to convey the meaning of statistical information. Pictographs should be used carefully because the graphs may, either accidentally or deliberately, misrepresent the data. This is why a graph should be visually accurate.

Histographs- I can truly see no difference between Bar graphs and histographs.

If you need me to summarize any information, I'd be honored to assist.
• Why you did not put in 8 9 10?
• He didn't put in 8 or any number higher because the range of the ages aren't higher than 7
• Can the "X" on a line plot mean more than 1?
• If it has an X= this number than yes, it can.
• Will I still be using line plots later on in math?
• You will probably will use line plots later, to figure out mean, median, and mode in maybe 4th or 5th grade.
• Instead of always drawing a line plot horizontally, can we draw it vertically?
• Um, I guess so, but then- how would you do it? I really don't know, but _I_ think it's easier to draw it horizontally. =)
