In statistics, a variable is an attribute of the sample population that is being studied. It can vary from member to member of the sample, and it can be just about anything. Color, size, height, weight, and any other attribute that can be measured or described can be a variable. There...
Statistics - Confounding (factor|variable) - (Confound|Confounder) In statistics, a confounding variable (also confounding factor, a confound, or confounder) is an extraneous variable in a statistical model that correlates (directly or inversely) with both the dependent...

Contrary to causal-comparative research, correlational research does not hold the cause and effort as its basis. This observational research aims to establish relationships between variables using statistics. It interprets and studies relations, trends, patterns in the data but does not find the cause...
Ordinal variables can be placed in a logical, meaningful order while the order does not matter for nominal variables. Dichotomous variables are those with only two possible categories. Read Qualitative Variable | Classification & Examples Lesson ...
The answers were recorded in a binary fashion: “yes” or “no”. 2.6. Statistical Analysis Descriptive statistics (mean, standard deviation, coefficient of variation) have been analyzed for the whole parameters. For quantitative data, the Kolmogorov–Smirnov test was used to establish whether the...
This paper analyses the impact of the diatomaceous earth/peat (DEP; 3:1) microbial carrier on changes in the bacterial microbiome and the development of biofilm in the anaerobic digestion (AD) of confectionery waste, combined with digested sewage sludge as inoculum. The physicochemical properties of...
To do so, open the data set in a spreadsheet program. Select all cells with data in the data set and copy. Remember to include variable names in the first row. In TOSMANA, select File>Import from Clipboard in the menu. The data will be loaded to the software and will replace existing...
Aquantitative analysisof risk focuses on building risk models and simulations that enable the user to assign numerical values to risk. An example of quantitative risk analysis would be aMonte Carlo simulation. This method—which can be used in a variety of fields such as finance, engineering, an...
