concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined as any deviation from the standard value

affects hematocrit values. Hematocrit levels rise with an increase in the number of RBC’s or a decrease in the plasma volume. An elevated hematocrit is most often associated with severe burns‚ diarrhea‚ and dehydration‚ where water in tissues decreases. The low level of plasma water concentrates the RBC’s leading to the condition‚ hemoconcentration. An elevated hematocrit may also be caused by an absolute increase in blood cells‚ called polycythemia. Decreased levels can be due to conditions including
