FINDING TRENDS/INTERPRETING GRAPHS

What is a trend? Take a few moments and write down your ideas. If we are talking about math, what do you think a trend means in math?

FINDING TRENDS/INTERPRETING GRAPHS Put simply, a trend is a pattern in the data.

FINDING TRENDS/INTERPRETING GRAPHS Let’s watch the Learn 360 video “Cyberchase: Return to Sensible Flats” to gain a better understanding of how we can spot trends in graphs and how we can use them to make predictions. While watching the video answer the questions on the next slide. bU bU

Cyberchase: Return to Sensible Flats Video Questions After constructing the first line graph what trend did they discover? What information were they able to gain? What information was gained from the second line graph? How did the pattern help them to gain this information? Using the third graph how were they able to predict where the water level would be in the near future?

Responses to Video Questions The water level went down steadily after a period of time. If it doesn’t rain soon the lake will dry up in about 4 more days. “No rain, no water in the lake”. They knew how much the water level had risen in 5 minutes. They then calculated where the water level would be if it continued to rise to the same level every 5 minutes.
