00:00:00.003 --> 00:00:04.735
Cari Julat dan Julat Pertengahan 
bg set no. berikut.

00:00:04.735 --> 00:00:06.923
Julat menunjukkan beza nilai

00:00:06.923 --> 00:00:08.738
bagi nombor-nombor.

00:00:08.738 --> 00:00:10.258
Utk mengira Julat,

00:00:10.258 --> 00:00:12.044
Julat = Nilai terbesar -

00:00:12.044 --> 00:00:14.506
nilai terkecil.

00:00:14.506 --> 00:00:15.833


00:00:15.833 --> 00:00:17.187
Dari set no. ini,

00:00:17.187 --> 00:00:18.055
nilai yg terbesar

00:00:18.055 --> 00:00:20.562
ialah no. yg dibulatkan, iaitu 94.

00:00:20.562 --> 00:00:23.191


00:00:23.191 --> 00:00:25.418


00:00:25.418 --> 00:00:27.481
Kita akan tolak dgn

00:00:27.481 --> 00:00:29.466
nilai yg terkecil.

00:00:29.466 --> 00:00:31.131
Dlm set ini, nilai terkecil

00:00:31.131 --> 00:00:32.320
ialah 65.

00:00:32.320 --> 00:00:33.959


00:00:33.959 --> 00:00:36.408
Maka Julat = 94 - 65

00:00:36.408 --> 00:00:38.133


00:00:38.133 --> 00:00:40.822


00:00:40.822 --> 00:00:42.562


00:00:42.562 --> 00:00:44.426
= 29

00:00:44.426 --> 00:00:48.165
Semakin besar Julat,

00:00:48.165 --> 00:00:50.969
semakin besar beza antara nilai
dlm set data.

00:00:50.969 --> 00:00:54.194
Semakin kecil Julat,

00:00:54.194 --> 00:00:58.557
semakin kecil beza antara nilai 
dlm data.

00:00:58.557 --> 00:01:01.552
Julat pertengahan sama maksud dgn 
Kecenderungan Memusat,

00:01:01.552 --> 00:01:05.297
atau Purata. 
Maka, Julat Pertengahan

00:01:05.297 --> 00:01:09.744
ialah Purata kpd 


00:01:09.744 --> 00:01:12.987
nilai terkecil + terbesar.

00:01:12.987 --> 00:01:17.786
Ingat, Julat = beza nilai.
Julat pertengahan = Purata nilai.

00:01:17.786 --> 00:01:27.272
Julat Pertengahan = (94 + 65) ÷ 2

00:01:27.272 --> 00:01:32.532


00:01:32.532 --> 00:01:39.697


00:01:39.697 --> 00:01:45.273
= 159/2,

00:01:45.273 --> 00:01:49.996
79.5

00:01:49.996 --> 00:01:52.810


00:01:52.810 --> 00:01:57.556


00:01:57.556 --> 00:01:59.886


00:01:59.886 --> 00:02:02.600
Inilah Julat dan Julat Pertengahan.
