  • Usulan Penelitian BAB III KERANGKA KONSEPTUAL DAN HIPOTESIS PENELITIAN Dr. INDRA Z, Sp.THT-KLProgram Studi Pendidikan Dokter Universitas Malikussaleh
  • Kerangka Konseptualő Kerangka konsep penelitian adalah suatu hubungan atau kaitan antara konsep satu terhadap konsep yg lainnya dari masalah yg ingin diteliti.ő Konsep adalah st abstraksi yg dibentuk dgn menggeneralisasikan st pengertianő Agar konsep dpt diamati dan dpt diukur, mk konsep tsb harus dijabarkan kedlm variabel2
  • Contoh:Ekonomi keluarga adalah suatu konsep,utk mengukur konsep ekonomi dptmelalui variabel pendapatan ataupengeluaran keluarga.Tingkat sosial adalah merupakan konsep,maka untuk mengukur tingkat sosialseseorang dapat melalui variabel2 danpekerjaan misalnya
  • PENDIDIKAN PERILAKU KUALITAS FISIK KUALITAS SARANA KEJADIAN DIARE. AIR BERSIH AIR BERSIH STATUS STATUS SOSIAL EKONOMI
  • Konsep2 (variabel2) yg akan diamati berdasarkancontoh tsb adalah pendidikan, perilaku, status sosial,status ekonomi, kualitas air bersih dan kualitassarana air bersih sebagai variabel bebas(independent variables) dan kejadian diare sebagaivariabel tergantung (dependent variables).Sekaligus penelitian ini akan membuktikan pengaruhdari tiap-tiap variabel bebas terhadap variabeltergantung. Namun demikian kualitas air bersihsebagai variabel dependen utk variabel2 bebas:pendidikan, kualitas sarana air bersih, statusekonomi dsb
  • Checklist: Yes/No Is the hypothesis worded that it can be tested in the experiment (testable)? Does the hypothesis include independent and dependent variables?
  •  Tentative statement that can be tested or investigated. Involves explanation of phenomenon and states idea about cause and effect Why? ◦ Short term: establishes a research strategy ◦ Longterm: you can answer a question!
  • Step 1  Base it on research question, intended experimental units, and variables of study Research Question Experimental units Independent Variables Dependent Variables
  • HypothesisWell formulated ( long-term or short-term)TestableNovel and originalObjectiveWhat can be accomplished with what will berequestedDirect the following designAll objective should have intrinsic linkage andsequentiallyarranged
  • Reseach hypothesis:The temporary answer to the research questionthat will be tested in the studyOnly for analytical studies (not for descriptive studies) ≠ statistical hypothesisPrimary research hypothesis: only 1 from primary objective for sample size calculationSeveral research hypothesis of similar importance from primary & secondary objective calculate samples size for each hypothesis and take the largest sample size.
  • CharacteristicsA major characteristic of a good research hypo-thesis is that it is consistent with previousresearchA good hypothesis states as clearly andconcisely as possible the expectedrelationship or difference between twovariablesA well-stated and defined hypothesis mustbe testable
  • Hypothesis Testing►Hypothesis refers to educated guess orassumption to be assumption tested►Hypothesis is formulated following thereview of related literature and prior to theexecution of the study► Setting up and testing hypotheses is anessential part of statistical inference►Types of hypotheses:1.Research hypothesis --HA.2.Null hypothesis --HO
  • Hipotesis Penelitianŏ Hipotesis adalah pernyataan sbg jawaban sementara atas pertanyaan penelitian, yg harus di uji validitasnya scr empirisŏ Tdk semua penelitian memerlukan hipotesis → survey atau studi eksploratif yg bersifat deskriptifŏ Dibedakan antara hipotesis penelitian (research hypothesis) dgn hipotesis dlm uji kemaknaan yi hipotesis nol dan hipotesis alternatif
  • Syarat hipotesis yg baik:1. Dinyatakan dlm kalimat deklaratif yg jelas dan sederhana, tdk bermakna ganda2. Mempunyai landasan teori yg kuat3. Menyatakan hubungan antara satu variabel tergantung dgn satu atau lebih variabel bebas.4. Memungkinkan di uji scr empiris5. Rumusan hipotesa hrs bersifat khas dan menggambarkan variabel2 yg diukur6. Dikemukakan a priori
