There are different ways to change tempo depending on what you want.
If you want to set the tempo permanently, add a tempo value from the Tempo palette.
If you already have a tempo value, you can edit it. If it's a metronome value, just double-click it and change the number. If it's a traditional Italian tempo marking (e.g., "Allegro" or "Lento"), you can modify the tempo it gives the score on the Properties tab of the tempo marking.
If, on the other hand, you simply want to change it temporarily, you can undock the Play Panel from the upper right. You do this by clicking the six dots just to the right of the Rewind / Play/Stop / Loop buttons. When undocked, it has a slider that allows you to temporarily slow or speed the piece by a percentage. This will affect any tempo markings in the score by the same percentage.
Check the Handbook for Tempo for more information.
