Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
The absolute value of the standard score becomes smaller.
The smaller the standard deviation, the closer together the data is. A standard deviation of 0 tells you that every number is the same.
No.
In the same way that you calculate mean and median that are greater than the standard deviation!
The answer will depend on the two units. It will entail multiplication by a number that is greater than 1 (or division by a number smaller than 1).
The Radius
The radius of the circle decreases when you make the circle smaller.
The absolute value of the standard score becomes smaller.
No.
The grains will get smaller.
Let sigma = standard deviation. Standard error (of the sample mean) = sigma / square root of (n), where n is the sample size. Since you are dividing the standard deviation by a positive number greater than 1, the standard error is always smaller than the standard deviation.
equations are for making a math sentence smaller and to replace big numbers

Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller. Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller. Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller. Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller.
It simply means that you have a sample with a smaller variation than the population itself. In the case of random sample, it is possible.
The greater than sign is >, the less than sign is <. Whichever equation is on the "pointy" side of the sign is always the smaller thing. (Remember, small side of sign = smaller equation).
