Brahe devoted quite a long time to getting exact measurements of the sky from his observatory. Kepler then analyzed the data and extrapolated laws of motion and discovered that orbits were elliptical. Using the 'scientific method' is a vague term. There was no initial hypothesis that they asked to my knowledge, which is a crucial step in the text book 'scientific method'. They just collected data and interpreted it.
They were both early observational astronomers. Some people believe that after Brahe's death, Kepler 'stole' his data and used it to develop Kepler's three laws of planetary motion.
Johannes Kepler
Kepler was Brahe's assistant. He continued to analyze Brahe's data after Brahe's died. Kepler determine that the planets revolve around the sun in elliptical, or ovalshaped, orbits. He also developed three laws that describe planetary motion. These laws are still used today. Hope I explained this clearly(:
Kepler used Tycho Brahe's data to establish the heliocentric theory of the solar system.
Kepler spent 20 years plotting the positions of the planet no he did not.

Tycho Ottesen Brahe (1546-1601) spent a long time taking exact measurements of the sky from his observatory. Johannes Kepler (1571-1630) assisted Brahe and analized the data and extrapolated "The laws of motion" and discovered orbits were elliptical.
Kepler
Kepler was Brahe's assistant from 1600 until Brahe's death in 1601. After Brahe's death, Kepler "stole" his data and worked with it for nine years until he came up with his final conclusion that the planets move in elliptical orbits around the sun, which remained in place and was the center of the universe. Brahe's data and measurements were the only ones accurate enough for Kepler to come to this conclusion.

Tycho Brahe
Johannes Kepler studied under Tycho Brahe starting in 1600. After Brahe died one year later, Kepler took over his position as astronomer to the court in Prague.
No, Tycho Brahe did, but Kepler just improved it and made it popular
Kepler's "running mate" would have to be Tycho Brahe. It was Brahe whose work (observations) Kepler used as a springboard to think about the motions of the planets and what mechanism could make them appear to do the things they did.
