The middle number in a set of data showing that half of the data falls and half comes after it?
median
What does box and whiskers mean for mathematics?
it means the middle number in upper half of the data a box and whisker plot is a line with a box and has 3 points on box ;; median in middle, lower quartile on left point, and upper quartile on left point. on the end of the line on the left put your lower extreme ;; and on the end of the line on the right put your upper extreme.
Do odd numbers have a middle number?
yes it is half like if u wanted to find the middle number of 5 it would be 2 and a half or 2.5
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 are the uses for median?
Helps you accurately measure the results of a population. It's simply the middle number in a data set, so half of the population is above and half of it is below. It is better than the mean since it is resistant to outliers.

median
The upper quartile of the data set?
the upper quartile is the median of the upper half of a set of data. ;p
What is the median of the upper half of the data set?
It is the upper quartile.

What is the upper half of the middle atmosphere in earth?
Mesosphere
What is the upper half of the middle atmosphere?
The upper half of the middle atmosphere is known as the mesosphere. It extends from about 50 to 85 kilometers above the Earth's surface. Temperatures in the mesosphere can reach as low as -90 degrees Celsius.

What is the value that falls in the middle position when the data is arranged in order from smallest to largest?
That's the median. (It is also the 50th percentile.) Exactly half the data lie above the median and half lie below it.For example, consider the following list of numbers: 4, 2, 6, 7, 3, 8, 9.Arranging the numbers from least to greatest, we get: 2, 3, 4, 6, 7, 8, 9.The number 6 is in the middle, so 6 is the median of the data set. If the number of data points is even and no one number is in the center, you must find the average of the two data points in the middle of the list to determine the median.
What does the median tell you about the data?
The median, by definition, tells you the "half way point" of your data. Exactly half of the observations in the dataset will be less than the median and half will be greater than the median.
How does finding the IQR hep you identify the variability of set of data?
The IQR gives the range of the middle half of the data and, in that respect, it is a measure of the variability of the data.
What is the median in a set of data?
The middle value so half the data is above it and half the data is below it. It is often used because extreme values tend to affect it less than other measures of central tendency. If you have an even number of data points, the median is the mean of those two points. ( So you add the two values and divided by two)
