Experimental Research: Internal Validity

Recommended: Increae external validity

I found it very interesting when talking about experimental research how important validity is. There were two types internal validity and external validity. Internal was more about manipulation/controlling and removing any influence of extraneous variables. By doing so the goal is to be assured that any observed differences between groups in the study is attributed only be differences in the independent variable (e.g., treatment, intervention, and instruction) and no other factors. So, my understanding of this concept is basically understanding and verifying that the research was done right. I was wondering if anyone else got the same conclusion and if there are any other important parts to my understanding of internal validity that I am

  • Construct, Internal, and External Validity

    648 Words  | 2 Pages

    Internal validity, unlike external and construct validity, deals with causal relationships. In other words, the question is whether any additional research that is found is actually associated with the study that is being conducted. The question, again, is whether we can be confident that the outcome of the study is a result of the experiment itself. What this means is that internal validity is the extent to which a change in a given variable is caused by the change in another variable.

  • Use of Experiments in Natural Sciences and in Sociology

    862 Words  | 2 Pages

    Use of Experiments in Natural Sciences and in Sociology Experiments are particularly important in natural sciences as they are the device used to either prove or disprove a hypothesis. Sciences such as chemistry or physiology operate in what is known as closed systems, where all the variables can be controlled. This means therefore that such experiments can be carried out, and effectively. Whereas it may be difficult in physical sciences to control the variables, and in sociology to recreate everyday life, natural sciences do not face the same overriding problems. What they are investigating is predictable and all that makes up the experiment can be controlled and changed in order to assess how true their hypothesis is.

  • Research Design Essay: Evaluation of the Design of an Experiment

    1578 Words  | 4 Pages

    The ability to describe and critically assess a design of any research trial can be beneficial in many various aspects. Firstly, it can assist in maintaining current knowledge through reading other empirical researches, developing critical and analytical thinking skills and to practice the research process in order to carry out further studies (Christensen et al., 2014). In the current trial, similar techniques will be employed to critically describe and assess the design in terms of raising any issues related to the experimental design. The present trial consists of an environmental psychologist hired to assess a data entry company’s employees work stations. The psychologist recommended ergonomic computer keyboards and ergonomic chairs to increase productivity and decrease negative physical symptoms. An experimental research was subsequently carried out to help the employer choose which ergonomic aid is more effective. This essay will attempt to critically assess the research design and suggest any possible improvements.

  • What Is Internal And External Validity In Scientific Research?

    1066 Words  | 3 Pages

    Internal validity refers to whether the effects observed in a study are due to the manipulation of the independent variable and not some other factor. In other words there is a causal relationship between the independent and dependent variable. External validity is the validity of generalized (causal) inferences in scientific research, usually based on experiments as experimental validity. In other words, it is the extent to which the results of a study can be generalized to other situations and to other people. Internal validity refers to the validity of the measurement and test itself, whereas external validity refers to the ability to generalize the findings to the

    Unethical experiments have occurred long before people considered it was wrong. The protagonist of the practice of human experimentation justify their views on the basis that such experiments yield results for the good of society that are unprocurable by other methods or means of study ( Vollmann 1448 ).The reasons for the experiments were to understand, prevent, and treat disease, and often there is not a substitute for a human subject. This is true for study of illnesses such as depression, delusional states that manifest themselves partly by altering human subjectivity, and impairing cognitive functioning. Concluding, some experiments have the tendency to destroy the lives of the humans that have been experimented on.

    External motivation comes from outside of our own brain. When you want to do a job because it will impress someone, or because you'll receive a prize for it, or because you'll be punished if you don't--that's an inducement that comes from outside your internal value system. Internal motivation is the driving force that comes from inside us, and causes us to do a good job because we feel good about ourselves when we accomplish something. When we are internally motivated, we operate according to our own values.

  • Hypothesis and Research Question

    541 Words  | 2 Pages

    Research questions are formulated in a study to inquire about variables, both independent and dependent variables, and the relationship between them. Research questions are categorized into two, that is, qualitative and quantitative research questions. Qualitative questions are used in qualitative research like case studies, surveys and action research where the approach is non-numerical and analyses special phenomena that occur in nature. Quantitative research on the other hand is more of a systematic approach with measurable numerical quantities that go through analysis to prove a hypothesis. Finally, the research hypothesis is either approved or disapproved with regards to the results of the analysis (Laureate Online Education B.V. 2010). Hypotheses differ from research questions in that, they are predictions that researchers come up with about variables and expected relationships between them (Creswell 2008). Hypotheses are mostly used in experimental exercises and are used in making comparison of groups. Hypotheses are basically formulated in two forms; null and directional hypothesis. Null hypotheses predict the lack of relationship between groups. Alternative hypothesis is categorized into two; directional hypothesis which predicts on an expected outcome and non-directional hypotheses which make predictions without specifying differences and relationships due to lack of past information that can be used to predict the differences. The difference between a hypotheses and a research question lies on the fact that a hypothesis is a tentative statement which is more precise/specific and predicts an outcome. A research question is a general statement compared to a hypothesis (eNotes.com, Inc 2011). A hypothesis predicts an outc...

I wanted to change this behaviour because as a newly full time student I have to adjust to not having a paycheck and living on my own. My hope was to form new good habits that will help me manage my money for the rest of my life. Additionally, I have been contemplation stage of change for sometime. This can be defined as the stage in which a person realizes that they want to change their situation, but have not made a commitment yet (Csiernik, 2016).
