Final answer:
Observations of mice's energy levels without numerical measurement are qualitative. The size of tumors provides quantitative data and is considered raw data. Metabolites in safety testing (MIST) involves analyzing quantitative data for statistical significance.
Step-by-step explanation:
When evaluating the energy level of mice treated with a drug, if the observation is based on visible activity levels and not measured numerically, it is considered a qualitative observation. Quantitative data is information that can be measured and written down with numbers, such as the size of tumors in mice. Thus, the size of the tumors measured at the end of the study would provide quantitative data.
The size of each tumor before processing the data would be considered raw data. Once the data is organized or summarized in any way, such as calculating the average tumor size, it becomes descriptive statistics.
For efficacy studies including anti-cancer drugs, tests on the mice need to be carefully chosen to accurately measure drug effects. Methods like respirometry can provide quantitative data on the mice's metabolism by measuring the rate of respiration, which can be altered by the presence of cancer or the effects of treatments.
In studies on metabolites in safety testing (MIST), numerical values referencing concentrations in different groups of mice provide quantitative data that can be statistically analyzed to assess the safety and impact of tested substances. Statistical analysis would typically involve identifying the known quantities, employing the correct distribution for hypothesis testing, calculating the p-value, and comparing it with a pre-conceived alpha level (such as α = 0.05) to determine the statistical significance of the results.
