What is non-directional research hypothesis?
A non-directional research hypothesis is a kind of hypothesis that is used in testing statistical significance. It states that there is no difference between variables.
What are the advantages and disadvantages of describing a relationship between variables in a written report?
The advantage is knowing what you are writing about, and why. The disadvantage is not doing the research,and not knowing what you are supposed to be writing about.
Which research method assesses how well one variable predicts another without demonstrating a cause-effect relationship between the variables?
There is probably no such study. A correlation or regression analysis works only with linear relationships. Any even function over a symmetric interval will give a correlation coefficient of 0; suggesting no relationship and so no predictive power. That is utter nonsense. If two variables are independent of one another but are affected by a third variable which is unknown to (or overlooked by) the experimenter then one of the two observed variables may appear to predict the other observed variable but that will fall apart if the unknown variable changes. For example observed variables: my age and number of cars in the country. Both related to time and fairly good predictive power. But the predictive power will fail if I move to Another Country.
Define multivariate analysis?
Multivariate is the study of random variables which are multidimensional. Multivariate study is based on the statistical principle of multivariate statistics, which involves observation and analysis of more than one statistical variable at a time. In design and analysis, the technique is used to perform trade studies across multiple dimensions while taking into account the effects of all variables on the responses of interest.Multivariate study in MarketingStatistical procedure used in market research where more than one variable is analyzed at the same time. The goal of multivariate study is to identify statistical relationships between the variables, such as the relationship of home and family, or to gauge the dependence of the variables on each other through techniques such as conjoint-analysisor multidimensional scaling. Multivariate study in Dental:A set of techniques used when variation in several variables has to be studied simultaneously. In statistics, multivariate analysis is interpreted as any analytic method that allows simultaneous study of two or more dependent variables.Multivariate study in http://www.answers.com/library/Sports%20Science%20and%20Medicine-cid-9961188A statistical technique in which several dependent variables are analyzed simultaneously. For example, in a study of muscle strength, data may be collected on the age, type of training, and sex of the subjects being studied. In multivariate analysis, the effect of each of these variables can be examined, and also the interaction between them.
What are the disadvantages of the experimental method?
The advantage...is that you research the answer on the other website...heheheheh...wahahahha...By: Kimberly A. BersabalFirst off ^^^ you are an IDIOT! a real answer would beThe potential disadvantages with the experimental method are that the lab setting may inhibit natural behaviour; findings may not generalize to real world (low ecological validity); potential for unethical or impossible experiment.A positive would be: that researchers can manipulate certain variables they want to determine how they effect other variables; therefore its considered thee most powerful research method!
Definition of ex post facto research?
Ex post facto research is a type of research design that investigates relationships between variables after they have occurred. In this design, the researcher does not have control over the independent variables, as they are pre-existing. The study is observational and looks for correlations or causality between variables that have already taken place in the past.
What is a relational study?
A relational study is a research method that examines the relationships between two or more variables to determine how they are connected or associated. These studies often involve analyzing data to identify patterns, correlations, or causal relationships between the variables being studied. The goal is to gain insight into how changes in one variable may affect another.
This is the type of research that describes the strength and direction of relationships between variables?
Correlational
What type of research is usually based on numerical measurements?
A type of research that is usually based on numerical measurements is known as quantitative research. This style of research is used to examine relationships among variables, describes variables, and is useful in determining cause and effect interactions between variables.
What is research methodology?
this method provides an explanation about the extent of relationship between two or more variables. it examines the relationships including similarities or differences among several variables.
What is explanatory reserch?
Explanatory research aims to explain the relationships between variables and phenomena by uncovering the underlying mechanisms and factors that influence outcomes. This type of research goes beyond describing a situation to understand why or how something occurs. It is often used to test hypotheses and establish causal relationships between variables.
Explanation of casual hypothesis in relation to research?
A causal hypothesis is a research that predicts cause and effects among variables to be studied and their relationships in arousal levels and performance.
What is comparative research methodology?
this method provides an explanation about the extent of relationship between two or more variables. it examines the relationships including similarities or differences among several variables.
What is an intervening variable?
An intervening variable is an internal state that is hypothetical in empirical research. It explains the relationships between variables being observed.
Is causation the focus of explanatory research?
Yes, causation is a central focus of explanatory research. Explanatory research aims to understand the relationships between variables and uncover the causes behind certain phenomena or outcomes. It seeks to explain why certain events occur and how variables are connected to each other.
Are controlled variables the sames as research variables?
yes
Does qualitative research not control variables?
Qualitative research does control some variables. Mediating variables are the type that researchers can intervene with during a quantitative study.
