Sai Lomte, Tarun. When data analysts apply various statistical models to the data they are investigating, they are able to understand and interpret the information more strategically. An important variable in my study is the number of children (usually mothers or fathers with more children feel more stress) and my subjects have between 1, 2 or 3 children. Present you results with any necessary charts and graphs, but do not discuss or analyze the numbers -- in a statistical report, all analysis should happen in the conclusion.

Statistical visualization – Fast, interactive statistical analysis and exploratory capabilities in a visual interface can be used to understand data and build models. Once you have calculated some basic values of location, such as mean or median, spread, such as range and variance, and established the level of skew, you can move to more advanced statistical analysis, and start to look for patterns in the data. You can run statistical comparison (for instance using paired sample ttest) if p value is less than 0.05, the two dataset are different. Free software options for data analysis and visualization. Without power analysis, sample size may be too large or too small. Matching in Quasi-Experimental Designs: Normative Group Equivalence.
