After gathering data on the number of siblings my classmates have, I noticed that the distribution is skewed to the right, as there are a few students with a large number of siblings which pulls the mean to the right. In this case, the median would be the most appropriate center as it is less affected by extreme values.
Assuming I collected data from 20 classmates, the mean of the number of siblings would be: (2+2+1+3+1+1+3+2+1+4+1+5+3+2+1+2+2+3+1+2) / 20 = 2.05. Therefore, the mean is approximately 2.05.
The median would be the middle value when the data is arranged in ascending order, which would be 2 in this case.
Thus, the best measure of center for the number of siblings for my classmates would be the median, which is 2.
You are trying to find the average number of siblings that your classmates have. In 3–5 sentences, explain whether the distribution of the data you gathered is symmetrical or skewed and if the mean or median would be the most appropriate center. Also calculate and state the mean and median in your response. Finally, state the best measure of center for the number of siblings.
