This field is central to much quantitative research that is undertaken within the social sciences. Quantitative research may involve the use of proxies as stand-ins for other quantities that cannot be directly measured. Tree-ring width, for example, is considered a reliable proxy of ambient environmental conditions such as the warmth of growing ...
For qualitative research, the sample size is usually rather small, while quantitative research tends to focus on big groups and collecting a lot of data. After the collection, the data needs to be analyzed and interpreted to arrive at interesting conclusions that pertain directly to the research question.

Usually, the researcher has a certain theory regarding the topic under investigation.
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of a parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
The research team’s tests revealed the water discharged from the plant near Tragadi Bandar was higher in oxygen-depleting contaminants and warmer than the Gulf of Kutch’s waters. Its temperature was 32 to 33 degrees Celsius, far higher than the gulf’s average surface temperature of 26.1 degrees.
Signs of cooling inflation paved the way for September’s first rate cut in four years, with economic data indicating a continued decline from a peak of 9.1% in June 2022 to rates that have ...
The city of Memphis, in its declination letter, acknowledged that the Justice Department found violations within the police department, but the specific violations were not made public until after ...
