Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.
Zigmanuir [339]
The mean is the average.
So, to find the mean you want o add up all of the numbers and then divide by the number of numbers.

49 + 49 + 54 + 55 + 52 + 49 + 575 = 363
363 / 7 = 51.85
Rounded to 52

For the median you want o line all of your number up from least to greatest and then find the middle number.

49,49,49,52,54,55,55

Your median is 52

The mode is the number that is listed most often

49 is listed 3 times
54 is listed 1 time
52 is listed 1 time
55 is listed 2 times

So, your mode is 49

The areas of 10 cities are given in the table.
Masteriza [31]
The range for the cities in the south is 145 larger than the range for the cities in the north.

We find the range by subtracting the highest and lowest values; in the North, we have:
305 - 58 = 247

In the South, we have:
503 - 111 = 392

The difference in the ranges is 392 - 247 = 145.
