How many 10000 are in 1000000?
Count the zeros: 4 in 10000, 6 in 1000000
Subtract 4 from 6 and you have 2

How do you solve a mean squared deviation?
You cannot "solve" a mean squared deviation". You can calculate it or use it, but there is nothing to solve!
How do you find smallest integar number from a set of numbers?
Start counting from ' 1 '. The first number you name that is
a member of the set is the smallest integer in the set.
Is there a difference between the 80th percentile and the top 80?
There is not a difference between the 80th percentile and been in the top 80. This is the same thing just written in different ways.
What describes how closely measurements are to each other and how carefully they were made?
precision
Does the strength of correlation depend on the direction?
Absolutely not. The simplest way to demonstrate this is to consider a measure of agreement - disagreement. If we scored it so that "strongly agree" is 5 and "strongly disagree" is 1, we would get one value of the correlation. If we reverse-scored it, we would get exactly the same value, but with the opposite sign. The strength of the correlation is the same, but the direction of the relation has switched. Another consideration is the fact that the actual strength of the correlation is based on the square of its value. 0.20 squared is 0.04; 0.40 squared is 0.16. A correlation of 0.40 is four times as strong as a correlation of 0.20. But when you square something, you automatically lose the sign. The square of a negative number is positive. So by definition, correlations of the same size but different signs are equal in strength.
How do you find the median value on a cumulative frequency?
set all you numbers up in order from smallest to largest. then find the middle. if there are two number in the middle, add them up and divide by two. Example: set of numbers - 8,6,3,4,10,15,36 put in order from smallest to largest - 3,4,6,8,10,15,36 now find the middle number - 8 8 is then my median of this sequence
In the round to given place value why do you have to add 1?
You only have to add 1 if you're rounding up.
Round 11.3 and 11.7 to the nearest whole number.
11.3 rounds down, so you just zero out the 3 and you are left with 11.
11.7 rounds up. If you zero out the 7, you're left with 11. But 11.7 is closer to 12 than 11, so you have to add 1.
