  1. TUTORIAL RANDOM SAMPLING Ms. Excel SPSS Minitab Stata Yim Rahman 09.6173 2KS2

  2. MICROSOFT EXCEL (generating any random numbers) • Ketikkan formula =RAND()*(b-a) a = batas minimum b = batas maksimum • Kloning hasilnya... [skrinsut]

  3. MICROSOFT EXCEL (generating integer random numbers) • Ketikkan formula =RANDBETWEEN(a;b) a = batas minimum b = batas maksimum • Kloning hasilnya... [skrinsut]

  4. SPSS (sampling) • Entry data... [skrinsut] • Data → Select Cases... [skrinsut] • Klik “Random sample of cases”, klik “Sample...”, tentukan “Sample Size”, “Continue”... [skrinsut] • Elemen yang beruntung akan diperlakukan khusus... [skrinsut] [skrinsut]

  5. MINITAB (WOR sampling) • Entry data populasi... [skrinsut] • Calc → Random Data → Sample From Columns... [skrinsut] • Di “Sample”, masukkan banyaknya sampel. [skrinsut] Di “rows from column(s)”, masukkan label kolom populasi (misal C1) Di “store samples in:”, masukkan label kolom destinasi penampung sampel (misal C4) OK [skrinsut]

  6. MINITAB (WR sampling) • Entry data populasi... [skrinsut] • Calc → Random Data → Sample From Columns... [skrinsut] • Di “Sample”, masukkan banyaknya sampel. [skrinsut] Di “rows from column(s)”, masukkan label kolom populasi (misal C1) Di “store samples in:”, masukkan label kolom destinasi penampung sampel (misal C4) Centang “Sample with replacement” OK [skrinsut]

  7. MINITAB(generating any random numbers) • Calc → Random Data → Uniform... [skrinsut] • Di “Generate [...] rows of data”, masukkan berapa baris angka yang akan dihasilkan Di “Store in column(s):”, masukkan label kolom destinasi Di “Lower endpoint”, masukkan batas bawah Di “Upper endpoint”, masukkan batas atas [skrinsut] OK [skrinsut]

  8. MINITAB(generating integer random numbers) • Calc → Random Data → Integer... [skrinsut] • Di “Generate [...] rows of data”, masukkan berapa baris angka yang akan dihasilkan Di “Store in column(s):”, masukkan label kolom destinasi Di “Minimum value”, masukkan batas bawah Di “Maximum value”, masukkan batas atas [skrinsut] OK [skrinsut]

  9. Stata(generating integer random numbers) • Entry data sebanyak yang diinginkan [skrinsut] • Input perintah gen namavariabel=int(a*uniform()) a=10 untuk max 9 a=100 untuk max 99 a=10n untuk max 10n - 1 [skrinsut] • Tampilkan data dengan perintah “list” [skrinsut] [skrinsut 2-3 digit]

  10. Stata(generating random numbers [0,1)) • Entry data sebanyak yang diinginkan [skrinsut] • Input perintah gen namavariabel=uniform() • Tampilkan data dengan perintah “list” [skrinsut]

  11. Stata (sampling) • Entry data populasi... [skrinsut] • Statistics → Resampling → Draw random sample [skrinsut] • Tentukan ukuran sampel [skrinsut] • Tampilkan data dengan perintah “list” [skrinsut]

  12. Sudah Selesai? • Terima kasih telah menyaksikan pertunjukan kami (baik secara sukarela maupun terpaksa, kami paham bahwa sesungguhnya tidur di kamar lebih enak daripada keluar dari kamar dan berjalan di bawah sorotan sang Mentari, kemudian menonton lelucon yang tak lucu). • Jika ada kekurangan, harap maklum, kami manusia tak luput dari kesalahan. Jika ada kelebihan, tolong dikembalikan, karena hutang adalah beban. Terima kasih. • Oh ya, futsal SRS-Bekisar vs Gen Y Imassi, 10 Nov 2010 pkl 21.05 di GOR Jaktim. Nonton ya... :D • 10 November, Hari Pahlawan, harinya arek-arek Suroboyo, harinya Jatim, harinya SRS-Bekisar, hehehe...

  13. Referensi • Tombol F1 untuk setiap program • www.stata.com • Pencarian dengan www.google.co.id • ‘Special’ thanks to: • Teman sekamar saya, initial KRRI, yang rela menahan hasratnya main CS dan PES, sehingga saya bisa pinjam laptopnya. • Teman begadang saya, initial MHF, yang rela terganggu kegiatan onlinenya, sehingga saya bisa numpang browsing.
