Graphing Data Flashcards
1
Q
Histogram
A
Similar to bar graph; uses class boundary and frequency
2
Q
Class boundaries
A
In class limits;
LL-0.5
UL+0.5
3
Q
Polygon
A
Similar to line graph; uses midpoint and frequency; add outer midpoints (add and subtract class interval) to form a polygon
4
Q
Midpoint
A
(UL + LL) / 2
5
Q
Ogives
A
Uses cumulative frequency (CF) < and > and lower class boundaries;
CF<, starts adding frequencies from the lowest class; consider lower class boundaries on the x-axis as less than of that boundary
CF>, starts from the highest class limit
