Claim 0:
1. An automatic analyzer for dispensing a sample and a reagent into a reaction vessel to react with each other and performing analysis of a liquid obtained by the reaction, the automatic analyzer comprising:
a computer;
an analysis unit, coupled to the computer, configured to perform the sample analysis and a quality control analysis of a plurality of quality control samples for ensuring quality of the sample analysis;
a storage unit, coupled to the computer, that stores a plurality of quality control results of respective quality control analysis previously performed by the analysis unit; and
a display unit, coupled to the computer,
wherein the computer is programmed to:
display, simultaneously, on a first screen, a graph and an information area, the graph having a first axis perpendicular to a second axis, the first axis indicating time and the second axis indicating measurement result values, the graph displaying a first measurement result of a first quality control sample and a first deviation value which is displayed a predetermined deviation from the first measurement result and displaying a second measurement result of a second quality control sample and a second deviation value which is displayed a predetermined deviation from the first measurement result, the first measurement value and the first deviation point being displayed on the graph with a first symbol and the second measurement value and the second deviation point being displayed on the graph with a second symbol, which is different than the first symbol, and a horizontal line indicating a predetermined mean measurement result value, the information area being displayed below the graph and displaying at least a predetermined mean measurement result value and the first measurement result corresponding to the first quality control sample in association with each other,
receive a selection of the first measurement value and upon receiving the selection of the first measurement value, display a vertical selection line through the first symbol,
receive, via a second screen, an input of a quality control result number that corresponds to one of the plurality of quality control samples, and
based on the selected first measurement value of the first quality control sample, execute a statistical calculation of the first measurement result of the first quality control sample and a measurement of the one quality control sample indicated by the input quality control result number measured before the first measurement result, and causes the display unit to display a statistical calculation result on a third screen of the display unit,
wherein the first measurement result of the first quality control sample and the first deviation value are displayed equidistant with respect to the horizontal line of the predetermined mean measurement value on the graph.
