sorry

3. Escuse me but I asked you to calculate the number of coins he won in the first game, not in all the games ! The mode is the number you can found by make this operation : “number maxi of coins won”-“number mini of coins won”. Bye !

4. And I’m sorry but you have one more time failed for the third quartil, I’ll explain you : you know that 10/4, it’s 2.5 so the first quartil is the number in the list which is the middle of the seconde and the third : 337, it’s correct, the second quartil is 5, it’s the average, so the third quartil is 5+2.5=7.5. It’s the number between the seventh and the eighth : (445+446)/2=445.5 !!!

5. The rest of your results is correct, very good !

6. Escuse me it’s not “dinish”but finsh, escuse me ! lol ^^
