What the median number for 4, 8 10 5 9

2 answers:

8 0

The median is equal to the average of the numbers
add up all of the numbers and divide that by the total number of numbers to get the average, or median
for example: the average of 13,20, 15, and 23 would be (13+20+15+23)/4=17.75

if you have the sequence of 4, 8, 10, 5, and 9, the average would be (4+18+10+4+9)/5 = 9

Hope that helps!

Actually, the median is not the same as the average.
The mean and the average are the same.
To find the median, put these numbers in order.
So 4, 5, 8, 9, 10. Now see which number is in the middle.
It is 8, so 8 is the median number.

A report includes a statement that the "average" test score of applicants to medical schools is 28.4. What is the role of the t

qaws [65]

Answer:

See explanation below.

Step-by-step explanation:

The average is measure of central tendency that is also called sample mean and is calculated from the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

This is an estimator of the population mean and is unbiased since the expected value for the estimator is the same parameter as we can see here:

$E(\bar X)=\frac{\sum_{i=1}^n E(X_i)}{n} =\frac{n\mu}{n}=\mu$

And is important because is the most common measure of central tendency reported on any study.

Is important to remember that this measure can be affected by outliers , for this case when we have outliers is better use the median as a measure of central tendency

A snail can move 5 inches in 6 minutes. At this rate, how many feet can it move in 48 hours?

Alex Ar [27]

Answer:

2400 inches or 2000 feet is the correct answer

there are 60 minuets in an hour, and 10 sets of 6 minuets, so you multiply 5 by ten to get 50

then you multiply 50 by 48 to get 2400

then you divide by 12 to get 2000 feet
