The mean salary is $42,000. Now, let's find the median salary. Arrange the salaries in order from lowest to highest:
Conclusion
$210,000 ÷ 5 = $42,000
$20,000, $30,000, $40,000, $50,000, $70,000
Reality: The median is more robust against outliers, but the mean can be more accurate in normally distributed data.
The mean is the average value, while the median is the middle value when the data is arranged in order.
$50,000 + $30,000 + $70,000 + $20,000 + $40,000 = $210,000
