Why do you have to order the data to calculate the median but not for the mean?
The median is the middle number of the distribution of data. That is why the data has to be sorted. To find the mean, add up all of the data, and divide by the number of data points. So it is not necessary to sort the data, to find the mean.At the median, half of the data points are greater than that, and half are less than that. Suppose you drove around town and recorded prices of gasoline, and you found the following: 2.75, 2.77, 2.77, 2.79, 2.79, 2.80, 2.99, 3.09, 3.09, 3.17, 3.19. Note that I went ahead and sorted them.The middle price $2.80 is the median. Half of the stations have a price lower than this price, and half of the stations have a price higher than this. Many times, this type of information is more meaningful than the mean price of $2.93.
What is the median price of a home in 1955?
In 1955, the median price of a home in the United States was approximately $18,000. This figure reflects the post-World War II housing boom, where demand for homes surged as returning veterans sought to settle down. Adjusted for inflation, this price would be significantly lower than modern home prices, highlighting the changes in the housing market over the decades.
The distribution of home prices in Nirvana is skewed to the left. The median price is 167900. What is the mean?
To calculate the mean, you need all of the individual price, add them and divide by the number of prices. The median is the middle figure when they are ranked. Example: To simplify, imagine there are 5 homes that have been sold and these figures are in thousands of dollars. 100, 100, 900, 1000, 1500 The Mean = (100+100+900+1000+1500)÷5= 720 The Median is the middle figure which is 900.
