Qualitative refers to what a sample is, while quantitative refers to how much of that materal is present.
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.
Qualitative analysis means just to detect the presence of a substance in the sample while quantitative analysis is the determination of that substance i.e., in which amount it is present in the sample.
they are both incredibly boring so no there is no difference ;)
Density is a quantitative property of minerals that can be measured by determining the mass of a mineral sample and dividing it by its volume.
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.

Random sampling techniques.
Quantilative is where quantitative and qualitative data start to blur. You can ask a question in a quantitative fashion (survey question) but if you have a small sample size, then you need to interpret the data qualitatively (e.g., few, some, most) as opposed to quantitatively (e.g., 10%). it can go the other way as well. If you have a qualitative exercise (e.g., highlighter exercise) that you deploy to a large sample size, you can interpret that data quantitatively (e.g., % who selected a certain area of the image).
Quantitative analysis of a blood sample is not useful for alcohol intoxication, as alcohol levels are typically measured using breath or urine tests due to their rapid absorption and elimination from the bloodstream.
Qualitative ELISA determines the presence or absence of a specific antigen or antibody in a sample. It provides a yes/no answer. Quantitative ELISA measures the amount of antigen or antibody present in a sample, providing a numerical value to indicate the concentration of the analyte.
