Numerical data identified and presented

Identifying Numerical Data in Human Biology

Numerical data, also known as quantitative data, measures things in numbers. In human biology, this might include numerical values representing blood cell counts, body temperature, or pulse rate.
In order to identify numerical data, you first need to understand the context of the study. What is being measured? Is it countable or capable of being expressed on a numerical scale?
Importantly, understand the units of measurement for your numerical data to ensure they are appropriate for what’s being investigated.

Presenting Numerical Data

Numerical data can be presented in a range of formats including tables, graphs, histograms, scatter plots, or line charts. The format depends on what best communicates the data.
When displaying numerical data, always include labels, such as the titles of axes on graphs, to make your data clear to the reader.
Be aware of and communicate statistical measures such as mean, median, and mode. These statistical calculations give insight into the distribution of your data.
Precision and accuracy should be a focus in presentation. Round figures to an appropriate number of decimal places and use consistent units throughout.

Interpreting and Evaluating Numerical Data

Interpretation involves taking the raw data and making statements about what it suggests or indicates in relation to your research question.
Don’t just look at the numbers; consider what they may represent in terms of human biology. Why are they significant?
Have an understanding of statistical significance to evaluate whether any differences you see in the data are due to chance or a meaningful effect.
Always consider sources of error which might influence the results. This might include equipment error or human error during data collection.

In order to excel in the interpretation, analysis, and evaluation of numerical data, a keen sense of observation, attention to detail, patience and strong mathematical skills are needed. Above all, remain scientific and objective.
