چکیده انگلیسی
Occurrence probability distribution (Gaussian distribution) test was carried out at selected fixed heights on the electron density profile, N(h), for selected hours around midday and midnight from representative months within 1995 and 1999/2000. The main objective of this work is to investigate the normality of the frequency distribution of the data sets around the mean value. Although the distribution is not perfectly symmetrical about the mean value, the results show that the percentage of data within ±1 standard deviation of the mean is at least 69% between 100 km and the F2 peak height around midday and midnight for all the selected hours and for the two years investigated.
