Statistics Module 2 – SLP Central Tendencies From the data that was collected from SLP 1, I will calculate the mean, median and the mode. The mean is the average of the numbers from my experiment. I added up all the numbers (time it took to complete quality control), then divide by how many numbers there are. It is the sum divided by the count. 2.7+ 2.9+ 2.9+ 3+ 3.1+ 3.2+ 3.2+ 3.2+ 3.3+ 4.5 = 32. 32 / 10 = 3.2 . My answer for the mean is 3.2 hours. The mode is the number that occurs most often. Looking at the set of data my “mode” is 3.2. During the 10 days I tracked how long it took to complete quality control, on 3 of the days it was completed in 3.2 hours. 2.7, 2.9, 2.9, 3, 3.1, 3.2, 3.2, 3.2 , 3.3, 4.5. The mode is highlighted in red. The median is the "middle number" (in a sorted list of numbers). To find the Median, I place the numbers in value order and found the middle number. Since there were an even amount of data values I took the average of the 2 numbers in the middle. 2.7, 2.9, 2.9, 3, 3.1, 3.2 , 3.2, 3.2, 3.3, 4.5. 3.1 +3.2 = 6.3. 6.3 / 2 = 3.15. The median is 3.15 hours. I highlighted the middle numbers in red. In conclusion the mean is the arithmetic average of the data collected which is 3.2 hrs. The mode for the data is the value that most frequently appears, which is also 3.2 hrs. The median is the middle data value when the data is arranged in ascending order. Since there is an even number of data entries the median is the result of the average of the two middle data collected, which is 3.15 hours even though the mean, median and mode are almost identical, the measure of central tendency that most accurately reflects the theoretical time to perform QC on the cobas (3.0 hrs.) is the median value. The numbers from the data I collected were right where I had anticipated them to be. As a shift supervisor I work with this analyzer on a daily basis. So depending on what is going on with the analyzer I would be able to make a reasonable prediction on the time it would take me to complete the quality control process.
