Type of variable BambangSubali Biological Edu Dept
The Type of Variable a. Independent variable: variable influence or have effect on dependent variable b. Dependent variable: variable influenced or give response to independent variable c. Antecendent variable: variable influence on independent variable d. Random variable: variable does not influence on dependent variable e. Moderator variable: variable influence on independent and dependent variables
The Kind Of Variable f. Suppressor /nuisance/extraneous/variable: variable besides on independent variable which influence on dependent variable This variable must be controlled become random variable/control variable In the research method, these variables must be described explicitly on procedure g. Substitute variable/observation: replacer variable/observation of dependent variable if the dependent variable is difficult to be observed h. Covariate variable/concomitant variable/co-variable: suppressor variable that uncontrollable, but it must be collected and calculated in data analysis
THE INFLUENCE OF PHOSPHATE FERTILIZER CONSENTRATION ON THE PRODUCTIVITY OF CORN SEED IND VAR : PHOSPHATE FERTILIZER CONSENTRATION AS FACTOR DECLARE THE NUMBER OF FACTOR LEVEL 3 LEVEL IN LABORATORY EXPERIMENT: 0 G/POLYBAG, 2 G/POLYBAG, 4 G/POLYBAG , OR 4 LEVEL IN FIEPD EXPERIMENT: 0 KG/HA, 10 KG/HA, 20 KG/HA, 30 KG/HA II. DEP VAR (AS PRIMERY OBSERVATION ): PRODUCTIVITY OF CORN SEED CAN BE MEASURED (WITHOUT SUBSTITUTE OBSERVATION/PARAMETER) III. SUPPRESSOR VAR : A. FROM OBJECT VARIETY OF CORN MENTION THE VARIETY OF CORN IN THE RISEARCH TITTLE VIABILITY OF CORN SEED DECLARE THE VIABILITY OF CORN SEED IF THE EXPERIMENT STARTED BY PLANTING THE SEED (OR DECLARE THE SEEDLING SIZE THE HEIGHT OF SEEDING IF EXPERIMENT SRARTED IN THE SEEDLING CONDITION)
B. MEDIA MEDIA DETERMINED BY LOCATION DECLARE LOCATION OF EXPERIMENT (WONOSARI LIME SOIL , , PONTIANAK PEAT SOIL) 2. LABORATORY EXPERIMENT MEDIA SOIL TYPES DECLARE THE SOIL TYPE IN THE RESEARCH PROCEDUR ADDITIONAL DROPSY FERTILIZER DECLARE THE ADDITIONAL DROPSY FERTILIZER ON THE SOIL THE SOIL HOMOGENITY DECLARE THE SOIL WAS MIXED IN ORDER TO HOMOGEN POLYBAG SIZE DECLARE THE VOLUME OR DIAMETER OF POLY BACK THE SOIL VOLUME DECLARE THE SOIL VOLUME IN EACH POLYBACK DAILY ADDITIONAL WATER DECLARE ADD WATER UNTIL THE SOIL BECOME SATURATED. C. CLIMATIC FACTOR 1. FILED EXPERIMENT DETERMINED BY MONTH OF EXPERIMENT IS IMPLEMENTED) 2. LABORATORY EXPERIMENT CLIMATE FACTOR DETERMINED BY THE CONDITION OF GREEN HOUSE
D. MEDIATOR VAR a) AS EXPLANATORY VAR (IF DATA WERE COLLECTED) DRY WEIGHT OF ROOT, STEM AND LEAFS b) AS INTERVENING VAR (IF DATA WERE NOT COLLECTED TO DESCIBE ON THE LITERATURE SUTDY) THE CON SENTRATION OF PHOSPHATE ON THE SOIL AFTER FERTILIZATION, INTENSITY OF ROOT ABSORBSION, INTENSITY OF METABOLISM PROCESSES, LOCATION OF DEPOSITION OR ACCUMULATION THE METABOLISM RESULT D. RANDOM VARIABLE EXAMPLE: SEX OF RESEARCER, UNIFORM OF RESEARCHER, SIZE OF VERTILIZER CONTAINER,
THE INFLUENCE OF THE LENGTH EXPERIENCE USING THE MASK WITHOUT STRAP IN THE TRADITIONAL DANCING ON THE SLOPE OF THE INCISOR TEETH Indep. Var : ? Dep. Var : ? Suppressor Var: ? Moderator var: ? Mediator var Explanatory and intervening var?
