Jawaban:
[tex]mean = \frac{(4 \times 4) + (5 \times 6) + (6 \times 10) + (7 \times 8) + (8 \times 6) + (9 \times 4) + (10 \times 2)}{4 + 6 + 10 + 8 + 6 + 4 + 2} \\ = \frac{266}{40} \\ = 6.65[/tex]
[tex]median \\ ada \: 40 \: data \: jadi \: data \: ke \: 20 + data \: ke \: 21 \: dibahagi \: 2 \\ data \: ke \: 20 = 6 \\ data \: ke \: 21 = 7 \\ jadi \: median = \frac{6 + 7}{2} = 6.5 \\ \\ modus = 6[/tex]
