3.4 Variabel Penelitian, Populasi dan Sampel Penelitian
3.4.1 Variabel Penelitian
a. Variabel Bebas
Variabel bebas (independent) adalah variabel yang menjadi sebab timbulnya atau berubahnya variable terikat (dependent). Variabel bebas dalam penelitian ini adalah metode pengujian kesesuaian keluaran tegangan tabung (kVp).
b. Variabel Terikat
Variabel terikat (dependent) adalah variabel yang di pengaruhi atau yang menjadi akibat karena adanya variabel bebas (independent). Variabel terikat dalam penelitian ini adalah hasil pengujian kesesuaian keluaran tegangan tabung (kVp).
c. Variabel Kontrol
Variabel kontrol adalah variabel yang dikendalikan atau di buat konstan, dalam hal ini variabel kontrol yang digunakan adalah pesawat sinar-X, kVp, mAs, FFD, lapangan penyinaran, digital multimeter test tool.
3.4.2 Populasi Penelitian
Populasi yang di ambil pada penelitian ini adalah semua nilai kVp yang terdapat pada pesawat sinar-X konvensional di Instalasi Radiologi RSUD DR. R. Soetijono Blora.
3.4.3 Sampel Penelitian
Sampel penelitiannya adalah nilai faktor eksposi yang digunakan saat pengambilan data penelitian ini adalah 40 kVp, 50 kVp, 60 kVp, 70 kVp, dan 80 kVp dengan menggunakan mAs 10 mAs.

3.4 Research Variables, population and Sample Research3.4.1 Research Variablesa Free Variable.Free variables (independent) variable that is being cause the onset or the above-mentioned bound variable (dependent). Free variables in this study is a method of testing the suitability of the output voltage of the tube (kVp).b. Bound VariablesA bound variable (dependent) variables that are in the influence or that becomes a result because of the free variable (the independent). Bound variables in this study is the result of testing the suitability of the output voltage of the tube (kVp).c. Variable ControlThe control variable is a variable that is controlled or made a constant, in which case the control variables used are plane x-ray, kVp, mAs, FFD, digital multimeter, shines field test tool.3.4.2 Research PopulationThe population in this research is to take on all the values of kVp on aircraft of conventional x-ray in Installation Radiology HOSPITALS Dr. r. Soetijono Blora.3.4.3 Sample ResearchThe research sample is eksposi factor value used when data retrieval research is 40 kVp, kVp, 60 kVp 50, 70, and 80 kVp kVp using mAs 10 mAs.

Variables 3.4 Research, Population and Sample Research
3.4.1 Research Variables
a. Variables
The independent variables (independent) variable that is the cause of the onset or change in the dependent variable (dependent). The independent variables in this study is a method of testing the suitability of the output tube voltage (kVp).
B. Bound variable
dependent variable (dependent) is the variable that influenced or which become due for their independent variables (independent). The dependent variable in this study is the result of testing the suitability of the output tube voltage (kVp).
C. Control Variables
Control variables are variables that are controlled or made constant, in this case the control variables used are X-ray plane, kVp, mAs, FFD, the irradiation field, the digital multimeter test tool.
