Problem number 1

Conditions: - Is it true:

Answer student: - - - a variation called the variability in the feature quantity units of statistical set

- A variation called the average value of the statistical units feature sosovokupnosti

- A variation called the absolute value of the characteristic statistical population

- Variation is called the relative value of a statistical population characteristic

- A variation called the group of units of a statistical population


Problem number 2

Conditions: - What do you think is the difference between the variation in space and time?

Answer student: - - - difference between the two does not exist

- The difference is that the variation in space - statistic (ie, constant), and in-BPE to time - dynamic

- Variation in space - volatility characteristic of individual territories and variation in time - change characteristic values \u200b\u200bin different periods or times

- The difference is in the fact that the variation in the space seen by one basis, and in time - according to another feature

- The fundamental difference between the concepts of no

- Linear coefficient of variation, the magnitude of variation, variance


Problem number 5

Conditions: - For relative performance variations include:

Answer student: - - - coefficient oscillations, linear coefficient of variation coefficient of variation

- The scope of variation, the average linear deviation, variance, standard deviation

- The coefficient of the oscillations, the magnitude of variation, variance

- The standard deviation, the linear coefficient of variation

- Linear coefficient of variation, the magnitude of variation, variance
