I can depict data using tables and line graphs • I can describe the distribution of data in table or graph using median, range, and mode.
What is a line graph? 1) A line graph is used to show data. 2) A line graph is used to show changes over time. 3) A line graph can show functions. http://www.mathgoodies.com/lessons/graphs/line.html
RANGE Find the point that is the GREATEST Find the point that is the least…… greatest – least =range
What was the range for the height of the plant? Find the point that is the GREATEST Find the point that is the least…… greatest – least = range
