Test №2 Statistics, part 2 - MEI

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

Problem number 3
Conditions: - Measures of variation - is:
Answer student: - - - absolute figures
- The relative performance
- Absolute and relative performance
- Grouped figures
- Mean values

Problem number 4
Conditions: - For absolute figures 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 standard deviation, the linear coefficient of variation
- 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
