Volumetric Analysis
Basically, the analysis of the measuring the amount or concentration of a substance by the volume it occupies
Gravimetric Analysis
Basically, the analysis of the measuring the amount or concentration of a substance by the mass of the substance
Control group
the standard to which comparisons are made in an experiment
experimental group
An experimental group is the group in an experiment that receives the variable being tested
Correlational research
Correlational research involves measuring two variables and assessing the relationship between them, with no manipulation of an independent variable. Correlational research is not defined by where or how the data are collected.
Descriptive research
Descriptive research aims to accurately and systematically describe a population, situation or phenomenon. It can answer what, where, when and how questions, but not why questions.
Survey research
Survey research is defined as “the collection of information from a sample of individuals through their responses to questions” (Check & Schutt, 2012, p. 160). This type of research allows for a variety of methods to recruit participants, collect data, and utilize various methods of instrumentation.
Quasi-experimental research
Quasi-experimental research involves the manipulation of an independent variable without the random assignment of participants to conditions or orders of conditions. Quasi-experimental design attempts to establish a cause-and-effect relationship by using criteria other than randomization.
experimental research
experimental research involves manipulating variables, observing outcomes, and drawing conclusions based on empirical evidence. Experimental research is a form of comparative analysis in which you study two or more variables and observe a group under a certain condition.
extraneous variable
An extraneous variable is any variable not being investigated that has the potential to affect the outcome of a research study.
moderator variable
A moderator variable is a qualitative (e.g., gender, SES) or quantitative (e.g., amount of social support) variable that affects the direction and/or strength of the relationship between an independent or predictor variable and a dependent or criterion variable.
intervening Variable
intervening variable is a variable that handles the change in the dependent variable due to the change in the independent variable. In other words, the outcome of the dependent variable is decided through the intervening variable which itself gets influenced by the independent variable.
confounding variable
A confounding variable is an unmeasured third variable that influences both the supposed cause and the supposed effect.
continuous variable
A continuous variable is defined as a random variable that can take on an infinite number of values within a certain range and is not countable.
