Is blood pressure an interval or ratio?
Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general “continuous ” category.
Therefore, normal theory type statistics are also used when a such a measure serves as the dependent variable in an analysis.
Counts are tricky..
What type of measurement is blood pressure?
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value.
What is the ratio of low blood pressure?
Low blood pressure, or hypotension, is rarely cause for concern — unless it’s extremely low and related to shock. Hypotension is commonly defined as a blood pressure less than 100/60 (pressure between 100/60 and 120/80 is considered optimal).
Is 162 high blood pressure?
Normal pressure is 120/80 or lower. Your blood pressure is considered high (stage 1) if it reads 140/90. Stage 2 high blood pressure is 160/100 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away.
