Q-sum chart

In a Q-sum the horizontal x-axis of the chart represents time. Each time a service event is recorded the bold black line moves up one unit if the cow conceives, or down one unit if not. Therefore, if the conception rate were 50%, the black line would be, on average, horizontal. The other lines represent the path that would be followed by the conception rate listed in green (>50%) or red (<50%) at the end of the line. The Q-sum provides a simple way of assessing overall rates and trends in conception. Printing the Q-sum details the services included in the graphic.
