What is the difference between qualtatative and qauntative?
Some methods provide data which are quantitative and some methods data which are qualitative. Quantitative methods are those which focus on numbers and frequencies rather than on meaning and experience. Quantitative methods (e.g. experiments, questionnaires and psychometric tests) provide information which is easy to analyse statistically and fairly reliable. Quantitative methods are associated with the scientific and experimental approach and are criticised for not providing an in depth description. Qualitative methods are ways of collecting data which are concerned with describing meaning, rather than with drawing statistical inferences. What qualitative methods (e.g. case studies and interviews) lose on reliability they gain in terms of validity. They provide a more in depth and rich description.
What is the difference between quantitative and qualitative data in statistics?
Quantitative data is data that is relating to, measuring, or measured by the quantity of something, rather than its quality. ex: the number of people in a townQualitative data is data that can be captured that is not numerical in nature ex: the color of people's skin.Thus, essentially the distinction is that quantitative data deals with numbers and numerical values of what is being tested, where as qualitative data deals with the quality of what is being tested.Qualitative data's description cannot be describe in numbers. Quantitative data's description ca only be described in numbers.
Why is quantitative observation more useful than a non-quantitative one?
Because quantitative observations focus on Money or quantity rather than the opposite. Hope that makes sense.
What is quantitative variable?
Quantitative comes from the word "quantity" meaning an exact amount. A quantitative variable, or answer, is one where an exact numerical value is expected, such as, Liz has 4 dogs. 4 is the quantitative value. Contrast this with qualitative, where an amount is given but without exact numbers. i.e. Liz has MORE dogs than Sue. * * * * * Or even Liz has Labradors, while her parents have Great Danes.
Your pregnancy blood test came back as 21941 what does that mean?
A qualitative hCG test detects if hCG is present in the blood. The result is either positive or negative.You have had a quantitative hCG test (or beta hCG) which measures the amount of hCG actually present in the blood. A beta hCG level of 21,941mIU/ml means you are over six weeks pregnant or if you know you are less than 6 weeks, pregnant there is more than one embryo.
