Independent work number 1
"Investigation of statistical information and its systematization using groups in the oil and gas industry"
1. Purpose
The aim is to identify the suitability of the statistical information for the study by defining its homogeneity. Statistical information is considered suitable for the study if it qualitatively homogeneous. The homogeneity of the statistical information is checked by calculating the statistical characteristics.
2. Go to work
1. Write out the initial information from the application of the embodiment in accordance with the serial number in the magazine. Build a table view.

2. Calculate the performance variations and determine the homogeneity of statistical information. Calculations will issue to the table view.

Independent work number 2
"Systematics and analysis of statistical data using analytical groups"
1. Purpose
The main objective of this lab - to consolidate and deepen the knowledge of students studying the course of general statistics on the topic: "Summary and grouping of statistical data", and acquire the skills of construction of analytical groups according to statistical observation.
2. Go to work
1. Background information is used to build groups of Part I (see Table 1).
2. From the factorial is to treat the symptoms of productivity and profit - efficient.
3. The ranking values \u200b\u200bfactorial trait in ascending order. The results of the ranking table issue in kind.

4. An analytical group on the specified condition. Auxiliary calculations arrange the table type.
5. The results of the calculation will issue to the table view.

Independent work №3
"Selective observation and its application in the oil and gas industry"
2. The order of performance
1. We write the initial information on the entire population, in accordance with the number of options. Arrange it in a table form:
Table 1
Background information (profit) № var. Name of the bank's profit
1 2 11
Sberbank of Russia 1 444
2 Russian Vneshtorgbank 317.1
3 Gazprombank 50.4
4 Sibinbank -2,407.8
5 ONEKSIMbank 216.2
6 National Reserve Bank 1.3
7 "Ak Bars" -5.3
8 International Industrial Bank -192.2
9 SBS-Agro 369.2
10 International Moscow Bank -86.8
......
199 "Nizhny Novgorod banking house" -28
2. Define the size of the sample on the basis of a predetermined condition of selective observation. The number of samples we will be 5% of the population that is 10 edenits.
3. Draw sample scheme again without re-sampling, using all methods of selection:
 self-casual;
 Mechanical;
 a typical;
