Absence Isn't a Sign that Grades
Decline |
Question:
Do you agree with the
conclusions?
|
 |
The titles state clear
conclusions. Colors were
used consistently.
There were more girls (51)
than boys (34), so using
percentages was a good idea.
However, the percentages
should have been calculated
separately for boys and
girls. The number of boys in
each category should have
been divided by the total
number of boys. Same for
girls.
The scatter plot shows all
of the data effectively.
This allows the viewer to
assess the relation between
grades and absence for
themselves. Use larger
labels for the graph axes
and legends.

Does sugar have an affect on
kids' choice of cereals? |
Question:
What factors other than sugar determine the cereal you eat?
|
 |
How much sugar does each
cereal contain? Present a
bar chart of sugar per ounce
for each cereal. Order the
cereals by amount of sugar.
Does Apple Jacks have more
sugar than Life? Does life
contain more than Cheerios?
Does Cheerios contain more
than Kix?
The line graph and bar chart
present the same data. The
line graph is inappropriate.
The title could state a
conclusion.

What Is The Most Popular Food
Served By A School Cafeteria? |
Question:
What title would you use?
What conclusion do you make?
|
 |
|
This chart was meticulously
constructed. |
Recommendations:
Eliminate the pie chart. It
adds nothing to the vertical
bar chart.
Reduce the number of numeric
labels and gridlines for the
vertical axes, particularly
for the line graph. Enlarge
these labels. The gridlines
are fine for the bar chart,
but label only at intervals
of 200 (e.g. 0, 200, 400,
600, etc.). Make gridlines
at intervals of 20 (e.g. 0,
20, 40, 60, etc.). and
labels at intervals of 40
(e.g. 0, 40, 80, etc.) for
the line graph.
Enlarge the names of the
meals, particularly for the
line graph. Possibly rename
the "Main Meal" to be the
"Daily Special".
Make the colors consistent
for the bar chart and the
line graph. This is very
important. |
