A neurology doctor, or neurologist, is a healthcare professional who diagnoses and treats disorders affecting the brain, spinal cord, and nerves. He or she can specialize in one area or work more broadly, and can also be either a primary care provider or work in consultation with other healthcare providers.
To find the median of a set of values with an even number of values, place the values in ascending or descending order, find the 2 middle numbers and add them together and divâ¦ide that total by 2 and that's the median.
Definition of Median: The median of a data set is the middle number when the set is sorted in numerical order. Since there was an odd number of data points above, going to the center to find 9 was easy. In an even-numbered data set, you take the mean of the middle two numbers.
