Analysis of the results obtained.
The first indicators to be analysed are the demographic indicators of the respondents.
Considering the distribution of respondents by age, the following trends should be noted.
Weighted average:
The mode is the value that appears most often in a set of data values.
Maximum reps at x = 22 (f = 65). Therefore, the mode is 22.
The median (Me) is the value falling in the middle of a ranked (ordered) population. Find xi at which the accumulated frequency S will be greater than ∑f / 2 = 98. This value is xi = 22. Thus, the median is 22.
The median serves as a good indicator for asymmetric data distribution, since even when there are data outliers, the median is more robust to the effects of outliers.
In symmetric distribution series, the value of the mode and the median coincide with the average value (xav = Me = Mo), and in moderately asymmetric series they relate as follows: 3 (xav-Me) ≈ xav-Mo
The range is the difference between the maximum and minimum v...
