The purpose of setting control limits for a control chart is to determine whether the values over time are within a stable and predictable range. One does this by looking for patterns in the values and determining whether any points fall outside the control limits. Therefore, both options A and B are correct as the control chart is used to discern patterns and determine if any points fall outside the control limits.
