Determine the median of blood sample triglycerides from the following data from a clinical test?

Determine the median of blood sample triglycerides (standard units) from the following data from a clinical test?

Solutions

Expert Solution

Solution:

Median in case of continuous class interval is given by:

l + {(N/2 - Cp) / f} . h

Calculate cumulative frequency, c.f and class mid points and proceed as follows:

 

Thus, the median of blood sample triglycerides from the given data from a clinical test is 45.75 standard units

 


The median of blood sample triglycerides (standard units) from the given data from a clinical test is 45.75
