Q. The median for the given set of six ordered data values is 26.5 .91221_4149What is the missing value?The missing value is □.
Understand Median Concept: To find the missing value in an ordered set with a median of 26.5, we first need to understand that the median is the middle number in a sorted list of numbers. Since we have 6 data values, the median will be the average of the third and fourth numbers when the data is ordered from least to greatest.
Identify Missing Value Position: We are given the ordered set as 9,12,21,_,41,49. The missing value is the fourth number in this list because the third and fourth numbers are the middle two numbers in a set of six.
Set Up Equation for Median: To find the median, we need to average the third and fourth numbers. We are told that the median is 26.5. Therefore, we can set up the equation (21+missing value)/2=26.5 to find the missing value.
Solve for Missing Value: Now we solve for the missing value: Multiply both sides of the equation by 2 to get rid of the fraction: 21+missing value=53.
Isolate Missing Value: Subtract 21 from both sides to isolate the missing value: missing value =53−21.
Perform Subtraction: Perform the subtraction: missing value=32.
