Define the term quantitative data .

Quantitative data is measurable information that can be expressed by numbers or placed into specific categories.

What is qualitative data ?

Qualitative data is descriptive information, usually written, that presents features in an intuitive way.

True or False? Primary data is collected first-hand, usually during fieldwork.

True. Primary data is collected first-hand, usually during fieldwork.

Define continuous data .

Continuous data is numerical data that can take any value within a given range.

What is a mass balance ?

A mass balance is the input, output, and distribution of water or carbon between its flows and transfers within each stage of the system.

What is the interquartile range (IQR) ?

The interquartile range (IQR) is the difference between the upper quartile (UQ) and lower quartile (LQ) of a dataset.

What is Spearman's rank correlation coefficient ?

Spearman's rank correlation coefficient is a statistical test to determine if two sets of numbers have a relationship, with values ranging from -1 to +1.

Define the term big data .

Big data are large datasets that need computational manipulation to show trends, patterns, and subsequent links.
