Asteroseismic data obtained by Kepler are giving us an unprecedented look inside stars of different types. These data allow us to determine the radii of stars with a precision of a few percent and also enable us to estimate the masses of single stars to a level of precision that allows bona fide tests of inputs to stellar evolution. Such high-precision measurements of stellar radii and masses enables population synthesis studies. Kepler has detected oscillations and measured oscillation parameters in hundreds of main-sequence and sub-giant stars and a few thousand red giants. These data allow us to seismically study stars as an ensemble and derive statistically significant results. In this talk I shall discuss some of the results obtained by the Kepler Asteroseismic Science Consortium while studying stars as an ensemble. I shall present results obtained for both field stars and stars in some of the open clusters in the Kepler field of view For the open clusters in particular, we show how the seismic data can be use to infer properties of the cluster as a whole.
