Keywords

💡Quantitative Research

Quantitative research is a method that focuses on collecting numerical data and analyzing it using mathematical and statistical methods. In the video, it is emphasized as a scientific approach to explain phenomena by measuring and analyzing data. This method is particularly useful in fields such as education, business, and healthcare, where objective and measurable data are crucial for making informed decisions.

💡Phenomenon

A phenomenon is described in the video as a peculiar or extraordinary event or situation that can occur in any discipline or organization. Quantitative research aims to explain these phenomena by attaching numeric values to relevant factors and variables, thereby making them measurable and analyzable through statistical methods.

💡Mathematically-based Methods

Mathematically-based methods refer to the use of mathematical techniques, particularly statistics, to analyze data in quantitative research. The video highlights that these methods are essential for interpreting the numerical data collected during the research process, ensuring that the findings are reliable and can be generalized to a larger population.

💡Statistical Analysis

Statistical analysis involves the application of statistical methods to analyze and interpret numerical data. The video underscores its importance in quantitative research, where it is used to identify patterns, relationships, and trends within the data, allowing researchers to draw objective conclusions and make informed decisions.

💡Variables

Variables are factors or characteristics that can change or vary within a study. In the video, it is mentioned that quantitative research focuses on measuring these variables by assigning numeric values to them, which helps in understanding the relationships between different factors and in establishing cause-and-effect relationships.

💡Reliability

Reliability refers to the consistency and dependability of the research findings. The video describes quantitative research as reliable because it uses large sample sizes and standardized procedures, which reduce the chances of bias and ensure that the results can be replicated in future studies.

Objectivity in research means that the findings are based on observable and measurable evidence, free from personal biases or subjective influences. The video highlights that quantitative research is objective because it relies on numerical data and statistical methods, which provide a clear and unbiased analysis of the research problem.

💡Generalization

Generalization is the process of applying the findings from a sample to a larger population. The video explains that quantitative research uses statistical methods to generalize its findings, making them applicable to a broader context, such as in educational assessments or business strategies.

💡Controlled Circumstances

Controlled circumstances refer to the conditions under which an experiment or study is conducted, where variables are carefully managed to ensure accurate and reliable results. The video points out that quantitative research often involves highly controlled environments to establish clear cause-and-effect relationships between variables.

💡Sample

A sample is a subset of a population selected for a study. The video emphasizes that in quantitative research, the sample is assumed to be representative of the population, which is crucial for the reliability and validity of the findings. A large and well-chosen sample ensures that the results can be generalized to the entire population.
