What is the correct term for a pattern of variation that is noted in given data set?
Variability (also called spread or dispersion) refers to how spread out a set of data is. Variability gives you a way to describe how much data sets vary and allows you to use statistics to compare your data to other sets of data. The four main ways to describe variability in a data set are: range.

Research article You may find them referred to as original articles, research articles, research, or even just articles, depending on the journal. Typically, especially in STEM subjects, these articles will include Abstract, Introduction, Methods, Results, Discussion, and Conclusion sections.
What is the scientific discipline that analyzes the similarities among individuals based on how biologically related they are?
Twin and adoption studies are two instances of a much broader class of methods for observing nature-nurture called quantitative genetics , the scientific discipline in which similarities among individuals are analyzed based on how biologically related they are.
Why is it important to use random assignment when determining which research participants will compromise the different treatment groups in the study?
Why is it important to use random assignment when determining which research participants will comprise the different treatment groups in the study? Random assignment balances out the differences that might naturally exist between participants.
What is systematic replication?
the process of conducting a study again but with certain consistent differences, often in an attempt to extend the original research to different settings or participants.
What is replication definition?

What is variation in statistics?
What are measures of variation in statistics? Measures of variation in statistics are ways to describe the distribution or dispersion of your data. In other words, it shows how far apart data points are from each other. Statisticians use measures of variation to summarize their data.
What is another term for variability in statistics?
Variability is also referred to as spread, scatter or dispersion. It is most commonly measured with the following: Range: the difference between the highest and lowest values.
What is quantitative research method?
Definition. Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.
What is descriptive research design?
Descriptive research design is a type of research design that aims to obtain information to systematically describe a phenomenon, situation, or population. More specifically, it helps answer the what, when, where, and how questions regarding the research problem, rather than the why.
Which of the following statements does best describe the role of the scientific literature in conducting research?
Which of the following statements best describes the role of the scientific literature in conducting research? Consulting and adding to the scientific literature is an integral part of the research process.
Which statement best describes the scientific method quizlet?
Which statement best describes the scientific method? The scientific method was a new way to solve problems and do research.
What are the various elements that should be described in the method section of the paper?
The methods section should describe what was done to answer the research question, describe how it was done, justify the experimental design, and explain how the results were analyzed.
Which type of articles typically include an introduction method results and discussion and report original empirical research?
Research articles, sometimes referred to as empirical or primary sources, report on original research. They will typically include sections such as an introduction, methods, results, and discussion.
What is IMRaD pattern?

This format is often used for lab reports as well as for reporting any planned, systematic research in the social sciences, natural sciences, or engineering and computer sciences.
What is an empirical article?

What scientific field attempts to identify and understand the relationship between one’s genetic code and their actions?
The scientific field of behavior genetics attempts to study these differences empirically, either by examining similarities among family members with different degrees of genetic relatedness, or, more recently, by studying differences in the DNA of people with different behavioral traits.
What are the variations among humans worldwide?

What is random assignment in scientific method?
Random assignment is a procedure used in experiments to create multiple study groups that include participants with similar characteristics so that the groups are equivalent at the beginning of the study.
What does random assignment of participants to experimental and control conditions help ensure?
Random assignment of participants helps to ensure that any differences between and within the groups are not systematic at the outset of the experiment. Thus, any differences between groups recorded at the end of the experiment can be more confidently attributed to the experimental procedures or treatment.
