� Also called Tally sheet
� A Check Sheet is a structured, prepared form
for collecting and analyzing data
� Examples:
- Student Attendance Sheet
- Marks Report Card
� Also called Ishikawa Diagram/ Fishbone
Diagram
� Looks like Fishbone!
� Causes are written on left side bones
� The Effect (the problem) is written on the
right side (Fish head)

Course
� This is a type of Bar Chart.
� This chart shows data distribution and
frequency.
� It visually represents data and summary can
be seen easily.

� Each value is represented by a location
(point) based on horizontal and vertical

� Control charts are graphs used to study how a process changes over time.
� Data is plotted in time order. � A control chart always has a central line for
the average� A control chart has an upper line for the
upper control limit (UCL) and a lower line for the lower control limit (LCL).
� It visually shows the process variation over time
