Final answer:
The median result is calculated by ordering all scores and identifying the middle score if there is an odd number of data points, or averaging the two middle scores if there is an even number of data points.
Step-by-step explanation:
To calculate the median result, you would organize all the scores from the smallest to the largest. If there is an odd number of scores, the median is the middle score. If there is an even number of scores, the median is the average of the two middle scores.
For example, when counting from the smallest value, if the median is located between the 20th and 21st values, you would take both values and average them to find the median. If these two values were both 24, then the median result would also be 24.
In a case where you have a data set like 1; 1; 2; 3; 4; 4; 5; 5; 6; 7; 7; 8; 9 and you want to calculate the median, you would look for the middle value in this ordered set. Since there are 13 values, the median would be the 7th value, which is 5.
However, if there were an even number of data points, like 14 observations, you would find the median between the 7th and 8th values. For example, if the 7th value is 6.8 and the 8th is 7.2, the median would be (6.8 + 7.2) / 2, which equals 7.
The median result is the middle value in a set of data when the data is arranged in ascending order. To calculate the median result for sector 20, you need to arrange all the results from lowest to highest and find the middle value.
For example, if the results for sector 20 are 15, 18, 20, 23, and 25, the median result would be 20. This is because it is the middle value when the data is arranged in ascending order.
