Research can be conducted through various methods, including qualitative and quantitative approaches. Qualitative research involves collecting non-numerical data, such as interviews and observations, to explore concepts and experiences. Quantitative research, on the other hand, relies on numerical data and statistical analysis to test hypotheses and identify patterns. Additionally, mixed-methods research combines both qualitative and quantitative techniques for a more comprehensive understanding of a research question.
When you formulate and test a statistical hypothesis, you compute a test statistic (a numerical value using a formula depending on the test). If the test statistic falls in the critical region, it leads us to reject our hypothesis. If it does not fall in the critical region, we do not reject our hypothesis. The critical region is a numerical interval.
Yes, quantitative research is typically based on numerical measurements. It involves the collection and analysis of data that can be quantified, allowing researchers to identify patterns, test hypotheses, and make statistical inferences. This approach often utilizes structured tools like surveys or experiments to gather measurable data, which can then be analyzed using statistical methods.
When a test measures the same value over time, it is called reliability. Specifically, this can refer to test-retest reliability, which assesses the consistency of results when the same test is administered to the same subjects under similar conditions at different points in time. High reliability indicates that the test produces stable and consistent results across repeated administrations.
by standard consistency test we determine standard consistency of cement which is denoted by p. as we know standard consistency value for a cement its value is used for making the paste for determining setting time, soundness, compressive strength of cement
Quantitative research is based on numerical measurements, such as statistics, percentages, and other numerical data. This approach involves collecting and analyzing data to draw conclusions and make predictions about a particular phenomenon. Quantitative research often utilizes statistical tools and methods to examine relationships between variables and test hypotheses.
It is important that the test an item in various ways, to different limits of accuracy and get inconsistent results covering similar performance aspects. With a test specification you can stipulate exactly what parameters are to be tested, to what tolerance of measurement by specific methods ensuring consistent testing is applied no matter who do the test

The internal test would be logical consistency. The external test would be observation of the real world.

The NIIT Aptitude Test is designed to test the student's reasoning, comprehension and behavioral skills. It is a multiple choice test consisting of four areas: verbal ability and communication skills, numerical ability, logical reasoning & creative problem solving and supporting personality traits.
The internal test would be logical consistency. The external test would be observation of the real world.
A valid test is not always a reliable test. Validity refers to whether a test measures what it claims to measure, while reliability refers to the consistency of test results over time. For example, a test designed to measure mathematical ability may be valid if it accurately assesses math skills, but if the test yields vastly different scores when taken multiple times by the same individual, it lacks reliability. Thus, a test can be valid in content but still unreliable in execution.
