todd recorded how many throws he took at each hole during his game at drifters disc golf course. disc golf game number of throws complete the sentences. the median of the data is _ throws. the mean is _ throws. if the outlier in this distribution were removed, the ______ would change. 3 ... 4 ... mean 3 ... 4 ... median 4 ... 4 ... mean 4 ... 4 ... median
Answer
Answer:
4 ... 4.5 ... mean
Explanation:
Step1: Find the number of data - points
There are 2 + 1+ 3+ 2 + 1=9 data - points.
Step2: Find the median
Arrange the data in ascending order: 1,1,3,4,4,4,5,5,9. Since (n = 9) (odd), the median is the (\left(\frac{n + 1}{2}\right))-th value. (\frac{9+1}{2}=5) - th value, which is 4.
Step3: Calculate the mean
The mean (\bar{x}=\frac{1\times2 + 3\times1+4\times3+5\times2 + 9\times1}{9}=\frac{2 + 3+12 + 10+9}{9}=\frac{36}{9}=4.5).
Step4: Identify the outlier
The outlier is 9 as it is far from the other data - points.
Step5: Analyze the effect of removing the outlier
If we remove 9, the new data - set is 1,1,3,4,4,4,5,5 with (n = 8) data - points. The new median is (\frac{4 + 4}{2}=4), and the new mean is (\frac{1\times2+3\times1 + 4\times3+5\times2}{8}=\frac{2+3 + 12+10}{8}=\frac{27}{8}=3.375). The mean changes while the median remains 4.
