What statistical method should be used to investigate height?
② northerners = (height cm- 150)×0.6+50.

Southerners = (height cm- 150)×0.6+48.

Normal weight: = SW SW× 0. 10

Overweight: = SW+SW× (0.11~ 0.20)

Mild: = SW+SW× (0.2 1 ~ 0.30)

Moderate obesity: = SW+SW× (0.3 1 ~ 0.30)

Severity: = SW+SW× (0.3 1 ~ 0.50)

Weakness: = SW-SW× (0.11~ 0.20)

Severe emaciation: = SW-SW×0.20 (and above 0.2 1)

Male standard weight (kg) = body length (cm)- 100.

Female standard weight (kg) = length (cm)-102

Second, the formula commonly used in the world to calculate people's weight and the calculation of body proportion (more suitable for orientals)

Standard weight = (height cm- 100)x0.9 (kg)

Standard weight (female) = (height cm- 100)x0.9 (kg) -2.5 (kg)

Normal weight: standard weight+-(how much) 10%.

Overweight: over standard weight 10% and under standard weight by 20%.

Mild obesity: 20% above standard weight and 30% below standard weight.

Moderate obesity: 30% above standard weight and 50% below standard weight.

Severe obesity: more than 50% of standard weight.

Standard body fat: body mass index = weight (kg)/{height * height (m)}
