Signs that do not have quantitative expression and are recorded as a text belong to the attribute signs

Which value does the dispersion of constant value equals?

If to all values of varying sign add or subtract one and non-zero number, the arithmetic average:

If all frequencies of the row of distribution increase or decrease in the constant number of times k, the arithmetic middling will increase or decrease in k times

What type of average is used for the generalized characteristic of the sign when  individual values of the studied sign and volume of phenomena are known, and the frequencies are unknown

What value of coefficient of variation shows that variation is moderate:

Intervals in which minimum and maximum values of a sign are known we call: Choose one correct answer:

Name the type of grouping that is used for studying the availability and direction of connection between signs, from which one is effective, and another - factor that affects the result:

Statistics – is:

What index characterizes the relative measure of variation of the sign in the statistical aggregate?
