What do these mean?
-data collection
-constructing and interpreting graphs
-drawing the line of best fit

They sound like objectives for a unit of a math or economics class.

Step-by-step explanation:

Data collection would most likely mean analyzing collected data (looking for trends).

Constructing graphs would probably mean making graphs from a set of data (plotting the information).

Interpreting graphs would mean the opposite of the above definition: would look at a graph and then put that information into written form/

Drawing a line of best fit means making a line on a graph that represents the average of all of the data on the graph.

I hope that this helps!
