1
00:00:00,003 --> 00:00:04,735
Cari Julat dan Julat Pertengahan 
bg set no. berikut.

2
00:00:04,735 --> 00:00:06,923
Julat menunjukkan beza nilai

3
00:00:06,923 --> 00:00:08,738
bagi nombor-nombor.

4
00:00:08,738 --> 00:00:10,258
Utk mengira Julat,

5
00:00:10,258 --> 00:00:12,044
Julat = Nilai terbesar -

6
00:00:12,044 --> 00:00:14,506
nilai terkecil.

7
00:00:14,506 --> 00:00:15,833


8
00:00:15,833 --> 00:00:17,187
Dari set no. ini,

9
00:00:17,187 --> 00:00:18,055
nilai yg terbesar

10
00:00:18,055 --> 00:00:20,562
ialah no. yg dibulatkan, iaitu 94.

11
00:00:20,562 --> 00:00:23,191


12
00:00:23,191 --> 00:00:25,418


13
00:00:25,418 --> 00:00:27,481
Kita akan tolak dgn

14
00:00:27,481 --> 00:00:29,466
nilai yg terkecil.

15
00:00:29,466 --> 00:00:31,131
Dlm set ini, nilai terkecil

16
00:00:31,131 --> 00:00:32,320
ialah 65.

17
00:00:32,320 --> 00:00:33,959


18
00:00:33,959 --> 00:00:36,408
Maka Julat = 94 - 65

19
00:00:36,408 --> 00:00:38,133


20
00:00:38,133 --> 00:00:40,822


21
00:00:40,822 --> 00:00:42,562


22
00:00:42,562 --> 00:00:44,426
= 29

23
00:00:44,426 --> 00:00:48,165
Semakin besar Julat,

24
00:00:48,165 --> 00:00:50,969
semakin besar beza antara nilai
dlm set data.

25
00:00:50,969 --> 00:00:54,194
Semakin kecil Julat,

26
00:00:54,194 --> 00:00:58,557
semakin kecil beza antara nilai 
dlm data.

27
00:00:58,557 --> 00:01:01,552
Julat pertengahan sama maksud dgn 
Kecenderungan Memusat,

28
00:01:01,552 --> 00:01:05,297
atau Purata. 
Maka, Julat Pertengahan

29
00:01:05,297 --> 00:01:09,744
ialah Purata kpd 


30
00:01:09,744 --> 00:01:12,987
nilai terkecil + terbesar.

31
00:01:12,987 --> 00:01:17,786
Ingat, Julat = beza nilai.
Julat pertengahan = Purata nilai.

32
00:01:17,786 --> 00:01:27,272
Julat Pertengahan = (94 + 65) ÷ 2

33
00:01:27,272 --> 00:01:32,532


34
00:01:32,532 --> 00:01:39,697


35
00:01:39,697 --> 00:01:45,273
= 159/2,

36
00:01:45,273 --> 00:01:49,996
79.5

37
00:01:49,996 --> 00:01:52,810


38
00:01:52,810 --> 00:01:57,556


39
00:01:57,556 --> 00:01:59,886


40
00:01:59,886 --> 00:02:02,600
Inilah Julat dan Julat Pertengahan.
