Question

A. Systolic Measurements Complete Table 16.2 with the systolic measurements for all recorded data segments. Note the pressure marker insertion point (where Director detected systolic) and where the first sound was detected with the stethoscope. Calculate the deltas between the trials for each condition and between the Marker and Stethoscope pressure measurements. measurement at the Table 16.2 Systolic Data Systolic mmHg Vabe At Marker | Marker Avg- First Sound | Sound Avg.

Diastolic Measurements Complete Table 16.3 with the diastolic measurements from each of the recorded data segments. Note the pressure measurement at the marker insertion point (when the Director detected diastolic) and where the sound disappeared. Calculate the deltas between the trials for condition and between the marker and the stethoscope measurements for each segment.

Explanation / Answer

1. The difference in measurement is due to errors of indirect measurement like observer bias, faulty equipment and failure to standarise the measurement technique. No other observer might not get same readings due to observer bias. Terminal digit preference and difference in auditory acuity of observers lead to observer bias error
