Theory of Statistics
Task 1
1. Construct a discrete and interval series of distribution and represent them graphically. The interval number divided into four groups with equal intervals closed.
2. Calculate the number of indicators of the distribution center (average number, fashion, median) and variation indices of interval ryadu.Sdelat analysis of the results.
Industrial profitability level,% 13, 18, 26, 10, 18, 15, 20, 24, 18, 15, 24, 20, 22, 18.

Task 2
1. Calculate the baseline (compared to 200 a year) and chain absolute and relative performance analysis of the dynamics of summary indicator values \u200b\u200b(first line).
2. Determine the average number of speakers.
3. identify the main trends of the dynamics of a number of methods of three-level moving average and the analytical equation for a straight alignment.
4. Calculate possible level summary measure for 2008 while maintaining the current trends, using average figures and analytical smoothing method.
5. Construct a line diagram of the dynamics of the original (actual) and calculated (theoretical) levels.
6. To study the changes in the structure of the indicator 200a, compared with 200 a year + 4. Show the relative values \u200b\u200bof the structure obtained in the form of pie charts.
7. Analyze all the results and draw conclusions.

According to the data below on the implementation of the three types of goods to determine:
1. Individual indices amount of goods sold and prices.
2. Summary (total) index turnover.
3. The price index Paasche system.
4. The composite index of the physical volume of realization.
5. To check the correctness of calculations using the relationship formula indexes.
6. Perform a factor analysis changes turnover, defining its absolute change due to changes in the number of sales and due to price changes.
7. To analyze the results and draw conclusions.
