a. Measure the collector to ground voltage and the emitter to ground voltage.
From your measurements, determine $V_{CE}$
b. Now calculate $V_{CE}$ by analysing the circuit. What differences do you find, if any?
c. Increase the base voltage to 5, 7.5 and 10 V and repeat (a) and (b). What do
you observe? What region is the transistor operating in?
