Statistics

Statistics often requires one to make estimates of some measure (variable) about a set of units. The total number of such units is the population size.

Note that population, in this context, need not refer to people. If the study is about household expenditure on food (in some area), then the population is all households and the population size is the number of households (in that area). If the study is about diversity of insects in a field, the population may be all 1-metre squares in the field, and the size of the population will be the number of such plots - which will equal the area of the field.

56 if digits can be repeated.

18 if they can't.

Sounds like a trick question, since twins will almost always be born on the same day.

Well bearing in mind that it may be completely out of context, I was asked the same question earlier by a friend... In his situation, I think someone had tried to call him a bastard, via SMS, with predictive text turned on.

+ and - are used to subtract and add, also to indicate if positive or negative. When the integer is positive you don't have to place a sign. When the _x wherein _ is equal to 1, you also don't have to place 1 beside x. That's stupidity.

Yes there is a cheat but they took it off.The cheat was you do nothing for 60sec and get 500 points.

If you have suffiecient rights to destribute a certain meterial to the public, Ie. Copyright Free or You made it yourself, then you would have full Distribution rights.

For median, add them together and divide by 2; (9+11)/2 = 10.

You arrange all of the numbers in a given set from least to greatest. The median number is the one in the middle. If there is an even number in the set, the median is the average of the two middle numbers.

It depends, if the random numbers are generated by computer, they can always be predicted if we know the code.

If they are picked from a hat, or by one of many other methods of picking truly random numbers, we cannot.

The mean is the same as the mode and median.

The average.

Well the three is in the ten thousands column and represents thirty thousand. That would be my choice.

0.2 meters

It's called the median point.

As one variable increases the other variable decreases.

you cannot predict how many times you get heads or tails but however you can predict the probability it will hit heads or tails only which is don by multiplying 1/2 by itself 5 times

If that's 3, 4, 6, 6, 6, add them up and divide by 5. The mean is 5.

A f r i c a !

Add the two in the middle and divide by 2
