The single phase double layered manganites La_{1.2}Sr_{1.8-x}Ca_xMn₂O₇ (x=0.0, 0.3) were synthesized by the sol-gel method. The electrical resistivity at various magnetic fields over a temperature range 4.2-300 K was measured. The insulator-to-metal transition temperature (T_{IM}) decreases from 123 K (x=0.0) to 70 K (x=0.3). The spin-glass (SG)-like transition is observed in both the samples at 30 K (T_{SG} - SG-like transition temperature). The transport behavior is analyzed in the entire temperature range (4.2-300 K) in three different regions: paramagnetic insulating region (T>T_{IM}), ferromagnetic metallic region (T_{SG}
