Is the variance of a group of scores the same as the sum of the squared deviations or the average of the squared deviations?
Given a set of n scores, the variance is sum of the squared deviation divided by n or n-1. We divide by n for the population and n-1 for the sample.
What is the sum of one and zero?
The sum of 0 and 1 is 1. 0+1=1 If you have 1, and you add 0(which is nothing), then you will still have 1.
Why does a squared plus b squared equal c squared?
Because the letters can represent any sum not necessarily its only on a triangle where that happens the hypotenuse squared equals the sum of the other two sides squared added together like if a was 1 and b was two c could be three so 1+4 doesn't equal 9
Is a minus b squared the same as a squared minus b squared?
No, unless "a" happens to be equal to 0, or to 1.
What is the sum of all possible values of x squared of an isosceles triangle that has two sides with lengths of 4 and x?
It is impossible to answer the question. In the specified isosceles triangle, x can have any value between 0 and 8. Therefore 0 < x2 < 64. There are infinitely many numbers between 0 and 1 (leave alone 0 and 64) and their sum is infinite.
Is the variance of a group of scores the same as the sum of the squared deviations or the average of the squared deviations?
Given a set of n scores, the variance is sum of the squared deviation divided by n or n-1. We divide by n for the population and n-1 for the sample.
Why do you divide by instead of when calculating the sample variance?
Usually the sum of squared deviations from the mean is divided by n-1, where n is the number of observations in the sample.
What is the sum 1 plus (-1)?
0
What is the sum of one and zero?
The sum of 0 and 1 is 1. 0+1=1 If you have 1, and you add 0(which is nothing), then you will still have 1.
Sum of x squared and x subtract x squared plus 1?
x^2 + x -x^2 +1 =x+1
Is standard deviation the arithmetic mean of the squared deviations from the means?
No. Standard deviation is the square root of the mean of the squared deviations from the mean. Also, if the mean of the data is determined by the same process as the deviation from the mean, then you loose one degree of freedom, and the divisor in the calculation should be N-1, instead of just N.
Why does a squared plus b squared equal c squared?
Because the letters can represent any sum not necessarily its only on a triangle where that happens the hypotenuse squared equals the sum of the other two sides squared added together like if a was 1 and b was two c could be three so 1+4 doesn't equal 9
Java code to find the sum in all integer?
The following will sum all integers from 1-100. Adjust according to your needs.int sum = 0;for (int i = 1; i
Is a minus b squared the same as a squared minus b squared?
No, unless "a" happens to be equal to 0, or to 1.
How do you write while andfor loop to get sum of1to100 integer?
int i, sum; /* example using while */ sum = 0; i = 1; while (i <= 100) { sum += i; ++i; } /* example using for */ sum = 0; for (i = 1; i <= 100; ++i) sum += i;
What two squared numbers add up 62?
There are no two whole numbers which when squared sum to 62. There are infinitely may pairs of irrational numbers that when squared sum to 62, eg 1 and √61, 2 and √58
What 3 consecutive integers have a sum of 0?
-1, 0, 1
