Reactivity is a rather subjective concept that relates, say, to how violently an element reacts. We all "know" that the alkali metals get "more reactive" as you go down the group, and this is usually explained in terms of falling ionisation energy - the ease with which an electron is removed from the outer level.
Electrode potential goes one step further than this, and includes a factor called hydration enthalpy. This may distort the trend - for example, you might expect that lithium is the least powerful reducing agent in Group 1, but, in fact, it has the most negative electrode potential of the lot because its ion is so heavily hydrated.
