The Benedict's qualitative test is called semi-qualitative since it is not totally conclusive.
Benedicts solution changes through a range of colours (blue, green, orange, red) according to how much reducing sugar is present in the sample. This can be used to give a rough answer to the question "How much sugar is in the sample?", but is not accurate enough (because of the blending between one colour and the next), to be called a quantitative test.
Semi = half
A tessellation that uses more than one kind of regular polygon is called a semi-regular tessellation.
If its 2d its called a semi-circle, if its 3d its called a semi-sphere.
Benedict solution is considered as a Simi quantitative test because of it's change in colour range depending to the number of reducing sugar in the sample being tested ,this can be use to determine the amount of reducing sugars but never totally conclusive
Benedict's test is considered semi-quantitative because it gives a general idea of the amount of reducing sugar present based on color changes, but it is not precise enough to give an exact concentration of sugar present. The test relies on color changes to estimate the relative amount of reducing sugar, making it qualitative and semi-quantitative rather than fully quantitative.

The qualitative reducing sugar test gives a positive or negative result, indicating the presence or absence of reducing sugars without precise measurement of quantity. However, by observing the color change and comparing it to a color chart, one can roughly estimate the amount of reducing sugar present, making it semi-quantitative. True quantitative analysis would involve measuring the exact concentration of reducing sugars present using specific equipment like spectrophotometers.
Semi-quantitative methods involve assigning categories or rankings to data, while quantitative methods involve measuring and analyzing numerical data. Semi-quantitative methods provide a general sense of trends, while quantitative methods offer precise numerical values for analysis.
Semi-quantitative analysis is important in estimating the concentration of a substance in a sample because it provides a rough idea of the amount present, which can be useful for quick assessments or comparisons. While not as precise as quantitative analysis, it can still give valuable insights into the sample's composition.
The key steps in conducting a semi-quantitative analysis involve defining the criteria for evaluation, assigning numerical values to these criteria, scoring the criteria based on their importance, and calculating an overall score by combining the individual scores.
The instruments of Qualitative research data collections are the following.: unstructured or semi structured observation form unstructured or semi structured questionnaire unstructured or semi structured interview
You get an accurate answer with it rather than using semi quantitative methods to get estimated results.
Data can be classified into various forms such as structured data (organized into rows and columns), unstructured data (text, images, videos), semi-structured data (mix of structured and unstructured data), quantitative data (numerical), qualitative data (descriptive), primary data (first-hand) and secondary data (collected by others).
