What level of measurement is body weight. The fourth and highest level of measurement is the ratio level. Weight is a ratio variable. Can be used in computations. When working with ratio variables but not interval variables the ratio of two measurements has a meaningful interpretation. The level of measurement refers to the relationship among the values that are assigned to the attributes for a variable. You simply step on the scale and the tool measures both your body weight and your estimated fat percentage.

Ratio level of measurement. Quantitative numerical values representing counts or measures. Data at the ratio level possess all of the features of the interval level in addition to a zero value. Due to the presence of a zero it now makes sense to compare the ratios of measurements. Something we can measure with a tool or a scale or count. 2 pounds is less than 4 pounds you can take a mathematical average of these values ie.

The simplest measurement scale we can use to label variables is. In this post we define each measurement scale and provide examples of variables that can be used with each scale.

Such scales work with the help of sensors underneath. We can compare these values on a number line.

Having excess weight can affect a persons risk of developing a number of health conditions including. Select compute bmi and your bmi will appear below. This means that you can construct a meaningful fraction or ratio with a ratio variable. The widely used body mass index bmi provides a measure that allows the comparison of the adiposity of individuals of different heights and weights.
