Question

shane checked the hit counters of 7 websites to track how many people visited them yesterday. he noted:
6 visitors 8 visitors 3 visitors 3 visitors 2 visitors 4 visitors 9 visitors
what was the mean absolute deviation of the numbers of visitors?
if the answer is a decimal, round it to the nearest tenth.
mean absolute deviation (mad): \boxed{} visitors

Explanation:

Step1: Calculate the mean

The mean $\bar{x}=\frac{6 + 8+3+3+2+4+9}{7}=\frac{35}{7}=5$

Step2: Calculate the absolute deviations

$|6 - 5|=1$, $|8 - 5|=3$, $|3 - 5|=2$, $|3 - 5|=2$, $|2 - 5|=3$, $|4 - 5|=1$, $|9 - 5|=4$

Step3: Calculate the mean of absolute deviations

The mean absolute deviation $MAD=\frac{1+3+2+2+3+1+4}{7}=\frac{16}{7}\approx2.3$

Answer:

$2.3$
