This paper presents the comparison of the absolute variability (σ) and relative variability (VR) of the critical frequency of F2-layer (foF2) at Ibadan (7.4°N, 3.9°E, 6°S dip) an equatorial station in the West African regionduring years of high, moderate and low solar activities for the seasons represented with the months of March, June, September and December are studied. Diurnal and seasonal variations of the absolute and relative variability obtained are compared. The results showed that relative variability of foF2 is more useful in representing the variability of foF2 than the absolute variability of foF2.
