What is the shape of a distribution when the mean and the median are the same value?
That would provide some evidence that the distribution is symmetric about the mean (or median).
How many five-digit whole numbers can be made with 1 2 3 and 4?
1024
If you're not allowed to use each digit more than once, then you can't make any 5-digit numbers, since you only have 4 digits to use.
I you can use each numeral (1, 2, 3, or 4) as many times as you want, then there are 4 ways to fill each position in the 5-digit number. The total number of possibilities is 45 = 1024.
Why is the mean and median not pratical when it comes to the mode?
The three are different measures of central tendency. None of them are substitutes for the other and, except in symmetric unimodal distributions, none of them can be used to estimate another.
How many 4 number combinations are there in the numbers 0 to 2?
Since there are only 3 digits available, repetition must be allowed.
In that case, there are 30 combinations.
When was The Distribution of the Eagle Standards created?
The Distribution of the Eagle Standards was created in 1810.
What do you want your residuals to be in statistics?
For the purpose of analyses, they should be independent, identically distributed random variables. But the ideal is that they are all 0.
What is the origin of unit measurements?

How do you find the range between the numbers -54 and 119?
to find the range of numbers, you take the largest number and subtract the smaller number. 119-(-54)=119+54=173
Assuming P(B) = 1/2 and P(G) = 1/2, the expected ratio of boys to girls would be:
B/G = 1.
Explanation:
Suppose 16 families. On their first child there would be 8 boys and 8 girls. From the
8 families that would try again their would be 4 girls and 4 boys. From the 4 families that would try again there would be 2 girls and 2 boys and from the 2 families that
would try again there would be 1 girl and one boy. Form the last family to try again
the chances of getting a boy or a girl is 1/2. So in a larger population than 16 families
half the time they would get a boy and half the time a girl. The relation of boys to
girls end up to be 1 to 1.
Better to plot the subjects' ages on the X-axis (horizontal) and their years of education on the Y-axis (vertical).
What is one thing that every equation contains?
An "equals" sign. That's why it is an equation, two parts are equal.
How many meters are there in 91.9 decimetres?
There are 10 decimetres in one metre. Therefore, 91.9 decimetres is equal to 91.9/10 = 9.19 metres.
How do you make the number 24 with the numbers 4 2 8 9 without using them more than once?
2x9+4+2. When you multiply 2 and 9 you get 18. Then when you add 4 you get 22. When you add 2 you end up with 24.
