This EMA covers some interesting data related to Gravitational Wave (GW) events. The detection of gravitational waves, which are ripples in space-time, make it possible to detect events such as black hole mergers that can not be seen through conventional telescopes. There have been 93 such events recorded to date, 90 are used in this data set. These GW events are mostly black hole mergers, but one of the more widely recorded events GW1T0817, is the merger of two neutron stars, the only such event recorded to date. In this EMA, you will analyse data relating gravitational wave events, all the initial data for this EMA are given in the file GW Data.mwx. The subsequent data tables used in this EMA are subsets or summaries of these initial data. In this GW Data.mwx file there are the following variables: GW Name: the name of the gravitational wave event, this is in the form GW followed by the year, month day, for instance GW1T0817 is the eravitational wave event recorded on the 17th August 2017, If there were two or more events on the same date, these have been labeled as "a', b, * GWTC run: the run in which the GW event was recorded. run 1 took place between 2015 and 2017, run 2 between April 2019 and Sept 2019 and run 3 took place between November 2009 and March 2020. + M1 source: the mass of source ohject 1, measured in units of solar masses the mass of the sun denoted as M. + M2 source: the mass of source ohject 2, measured in solar masses, M. Luminosity distance: the distance to the GW event, based on it's lnminosity measured in Mpe. * Spin: the effective spin of the GW event. + Total mass: the total mass of the GW event {in solar masses, M. Chirp mass: a measure of the effective mass of the binary system that produces the GW event (in solar masses, M. * Redshift: a measure of how much the light from the GW event is shifted towards the red part of the electromagnetic spectrinm. Final mass: the final mass after the GW event merger (in solar masses, M) You are strongly recommended to use Minitab where appropriate, but you are not required to do so.
