Do line graphs have to start at zero?
no but bar graphs do have to start at zero
Why do bar graphs have to start at zero but line graphs do not?
line graphs show a change over time
Do graphs have to start at the number zero?
yes a graph has to start from a point 0.
Must graph scales start at zero?
No. And for examples where they don't look at graphs where the x-axis is years. If the scales do not start at zero, this fact should be clearly indicated.
Do bar graphs start at the number zero?
A bar graph's data doesn't always start with zero but the scale on the y axis should. If you are not going to start the scale with zero then you have to put a squiggly line at the bottom to show that you skipped this space.
Do all like graphs have to start at 0?
Nope.
How can data be misrepresented in graphs?
If scales are too big, the right picture to represent an item displayed on a graph is not used, or if the graph doesn't start on zero, all are ways the data can be misrepresented!
What is a common misuse of graphs?
have no zero point
Do all number rules have to start from zero?
No.
What is a type of graphical graph?
All graphs are graphical graphs because if they were not graphical graphs they would not be graphs!
Why do some graphs not start at the origin?
Because not all equations have the co-ordinates 0,0 in their data range.
Do conversion graphs have to start at 0?
nope!
