finding the median from a dot plot\nthe dot plots show rainfall totals for several spring storms in highland…

Explanation:

Step1: Count data - points for highlands

Count the number of dots in the highlands dot - plot. There are 50 dots.

Step2: Calculate median position for highlands

Since (n = 50) (an even number), the median is the average of the (\frac{n}{2})th and ((\frac{n}{2}+ 1))th ordered data - values. (\frac{n}{2}=25) and (\frac{n}{2}+1 = 26). Counting from the left on the highlands dot - plot, the 25th and 26th ordered values are both 16. The median for highlands is (\frac{16 + 16}{2}=16).

Step3: Count data - points for lowlands

Count the number of dots in the lowlands dot - plot. There are 30 dots.

Step4: Calculate median position for lowlands

Since (n = 30) (an even number), the median is the average of the (\frac{n}{2})th and ((\frac{n}{2}+ 1))th ordered data - values. (\frac{n}{2}=15) and (\frac{n}{2}+1 = 16). Counting from the left on the lowlands dot - plot, the 15th value is 12 and the 16th value is 12. The median for lowlands is (\frac{12+12}{2}=12).

Answer:

Median for highland storms: 16 Median for lowland storms: 12
