Trend Lines

In class we were elaborating more on things in graphs. We rediscussed what need to be in the geaph wich we reviewed on the 26th. today we learned what a trend line is. We also dinfined these terms.

Trend Line- a line that traces a pattern, even if the dots arent connected. the line shows around the average of the data.

Trend- a pattern.

we put a trend line in our growth of plants graph, and there was dots on the top and the bottom. seeing that we realized that the trend line shows the average of the data. remember not to draw a straight line connecting the dots but draw a general pattern of the data.
