Interval Scale of Measurement (ISM) - selesai

Interval Scale of Measurement (ISM), selanjutnya saya sebut dengan singkatan ISM untuk memudahkan saya dalam memberi judul, biar tidak terlalu panjang. Mengulang lagi pembagian ISM kemarin yang terbagi menjadi 6, yaitu: (1) Central Tendency, (2) Frequencies, (3) Dispersion, (4) Symmetry, (5) Peakedness dan (6) Normality.

Sedangkan pemilihan statistik untuk ISM: Central Tendency sudah dibahas, sekarang adalah kelanjutan dari pemilihan ISM lainnya.

Frequencies

Statistical Test

Relative frequencies (e.g., percentages),

or Absolute frequencies,

or N-tiles

Statistical Measure

(none)

Sumber:

Blalock, H. M., Jr. Social Statistics. Second edition, revised, New York: McGraw-Hill, 1979. p. 31

Blalock, H. M., Jr. Social Statistics. Second edition, revised, New York: McGraw-Hill, 1979. p. 5\

Blalock, H. M., Jr. Social Statistics. Second edition, revised, New York: McGraw-Hill, 1979. p.19

Jika menggunakan Relative frequencies atau Absolute frequencies di SPSS menggunakan Frequencies dan di SAS menggunakan univariate atau chart. Sedangkan untuk N-tiles di SAS dengan menggunakan univariate.

Dispersion

Statistical Test

Standard deviation,

or coefficient of variation,

or range

Statistical Measure

(none)

McNemar, Q. Psychological Statistics. Fourth edition. New York: Wiley 1969. p. 19

Jika menggunakan standard deviation:

Spss : Condescriptive, Frequencies

Sas : Univariate, Means

Jika menggunakan coefficient of variation:

Sas : Univariate, Means

Jika menggunakan range:

Spss : Condescriptive, Frequencies

Sas : Univariate

Symmetry

Statistical Test	Skewness
Statistical Measure	(none)
Notes	To test departures from normality: for N greater than 150, refer the critical ratio of the skewness measure to a table of the unit normal curve; for N between 25 and 150, refer the skewness measure to a table for testing skewness. This is a biased estimator.
SPSS	Condescriptive, Frequencies
SAS	Univariate, Means

Peakedness

Statistical Test	Kurtosis
Statistical Measure	(none)
Notes	To test departures from normality: for N greater than 1000, refer the critical ratio of the kurtosis measure to a table of the unit normal curve; for N between 200 and 1000, refer the kurtosis measure to a table for testing kurtosis; for N less than 200, use Geary's criterion. This is a biased estimator.
SPSS	Condescriptive, Frequencies
SAS	Univariate, Means

Kurtosis: McNemar, Q. Psychological Statistics. Fourth edition. New York: Wiley 1969. p. 25

Geary's criterion for kurtosis: D'Agostino, R. B. Simple compact portable test of normality: Geary's test revisited. Psychological Bulletin 74 (1970):138-140.

Normality

Statistical Test	Kolmogorov-Smirnov one sample test, or Lilliefors extension of the Kolmogorov-Smirnov test, or the Chi-square goodness of fit test
Statistical Measure	(none)
Notes	To test departures from normality: for N greater than 1000, refer the critical ratio of the kurtosis measure to a table of the unit normal curve; for N between 200 and 1000, refer the kurtosis measure to a table for testing kurtosis; for N less than 200, use Geary's criterion. This is a biased estimator.

Jika menggunakan Kolmogorov-Smirnov

SPSS : NPAR

Jika menggunakan Lilliefors :

SAS : Univariate

Jika menggunakan Chi-square:

SPSS : NPAR

SAS : FREQ

Lihat juga: Skewness, Kurtosis

Dengan ini maka selesai sudah pemilihan jenis analisis statistik menggunakan satu variabel sudah selesai. Insyaallah sesudah ini menggunakan dua variabel.

Catatan:

Untuk lebih jelasnya, silakan berkonsultasi dengan dosen pembimbing saudara. Lebih baik jika Anda mempersiapkan proses bimbingan dengan melakukan pencarian di internet mengenai hal terkait. (membaca sumber yang saya cantumkan).

Tahukan Anda...

Hmm, it’s have been a while (a while???) since last time i wrote here. Skripsi is Indonesian terminology for a formal and lengthy research paper, especially a work of original research written in partial fulfillment of the requirements for a bachelor’s degree. I’m not sure about the equal English terminology for the Indonesian phrase strata satu, bachelor is the closest possible word that came into my mind. Whatever it is, with so many things in my mind, trying to share it with the entire world. :)
