Question

tolongin pleasee, kalau bisa pake cara yaa... ​

Answer 1

1. Nila ualangan Matematika Samsudin

• Mean = 7,1
• Median = 7
• Modus = 7 dan 8

2. Nilai UH Matematika kelas 5C SD

• Mean = 8,45
• Median = 9
• Modus = 9 dan 10

Pendahuluan:

1. Mean; merupakan rata-rata nilai dari/dalam sebuah data.

2. Median; merupakan nilai tengah dari/dalam sebuah data.

3. Modus; merupakan nilai yang paling sering banyak muncul dari/dalam sebuah data

Langkah-Langkah

1. Nila Ulangan Samsudin⤵️

Mean

5+6+6+7+7+7+8+8+8+9 ÷ 10

= 71 ÷ 10

= 7,1

Median

5, 6, 6, 7, 7, 7, 8, 8, 8, 9

Nilai tengah terdapat 2 angka, maka;

7+7 ÷ 2

= 14 ÷ 2

= 7

Modus

5, 6, 6, 7, 7, 7, 8 8, 8, 9

Modusnya 7 dan 8

2. Nilau UH Kelas 5C

Mean

6+7+7+8+8+9+9+9+10+10+10 ÷ 11

= 93 ÷ 11

= 8,45

Median

6, 7, 7, 8, 8, 9, 9, 9, 10, 10, 10

Nilai tengah/median = 9

Modus

6, 7, 7, 8, 8, 9, 9, 9, 10, 10, 10

Modusnya 9 dan 10

Answer 2

1. Mean :

= (7 + 6 + 6 + 7 + 8 + 9 + 8 + 7 + 5 + 8)/10

= (13 + 13 + 17 + 15 + 13)/10

= (26 + 32 + 13)/10

= (58 + 13)/10

= 71/10

= 7,1

Median :

Diurutkan : 5, 6, 6, 7, 7, 7, 8, 8, 8, 9

Median = (7 + 7)/2

= 14/2

= 7

Modus :

5 = 1

6 = 2

7 = 3

8 = 3

9 = 1

= 7 dan 8

2. Mean :

= (10 + 9 + 10 + 8 + 9 + 10 + 9 + 7 + 6 + 7 + 8)/11

= (19 + 18 + 19 + 16 + 13 + 8)/11

= (37 + 35 + 21)/11

= (72 + 21)/11

= 93/11

= 8,45

Median :

Diurutkan : 6, 7, 7, 8, 8, 9, 9, 9, 10, 10, 10

Median = 9

Modus :

6 = 1

7 = 2

8 = 2

9 = 3

10 = 3

= 9 dan 10
