Common Mistakes in Graphing:
Incorrect Axis Scaling
Many students don't use the same scale on the x-axis and y-axis.
For example, they might mark the x-axis with numbers going up by 1, but the y-axis goes up by 2.
This can make the graph look different than it really is.
Neglecting to Plot Points Accurately
A lot of students place points in the wrong spots when they plot them.
Research shows that about 30% of graphing mistakes happen because points like (3, 4) or (-2, -5) are not put in the right places.
Forgetting to Label Axes
Many students forget to label their axes.
This can make it hard to understand what the graph is showing.
Almost 25% of students skip putting units or names for the variables on their graphs.
Choosing the Wrong Type of Graph
Sometimes, students pick the wrong type of graph.
For instance, they might use line graphs when they should be using scatter plots.
Statistics reveal that about 20% of students are confused about which graph to use for different kinds of data.
