Final answer:
The median of the provided LDL values is 82. You find the median by arranging the values and choosing the middle one. In this case, the 6th value in the ordered list is the median.
Step-by-step explanation:
The student has asked to calculate the median value of LDL levels measured after patients were on medication for 3 months. LDL levels are important because they are a type of cholesterol, often referred to as 'bad cholesterol,' and high levels can lead to health risks such as heart disease. Calculating the median of a set of numbers involves arranging the numbers in order (which they already are) and finding the middle value. Since there are 11 values listed, the median will be the 6th value when the values are listed in ascending order.
