Testing of Statistical Hypotheses about The Distribution Laws of Deviations Probabilities of The F2 Layer Critical Frequency for The Longitudinal Chain of Observation Stations

A comparative analysis of the distribution histograms of deviations of the ionospheric F2 layer critical frequency from the median value at different solar activity, different seasons, different times of day and different latitudinal locations of the stations is carried out. Assumptions are made about the law of the distribution of the probabilities of deviations of the critical frequency of the F2 layer of the ionosphere. The dependence of the shape of the histogram of distribution on the above factors was determined. Examples of distribution histograms and values of their characteristics are given.
