SEP4: Analyzing and Interpreting Data — The Wonder of Science
Oct 22, 2020 discussion some researchers are calling for a move away from using statistical significance towards meaningful interpretation of findings.
Authors and readers alike often succumb to the temptation to over-interpret the results of statistical studies.
Interpretation is the process of making sense of numerical data that has been collected, analyzed, and presented. People interpret data when they turn on the television and hear the news anchor reporting on a poll, when they read.
Summary statistics help to analyze information about the sample data. It indicates something about the continuous (interval) and discrete (nominal) data set variables.
Statistical tests can be used to explore the relationships found in your data. Common statistical tests include chi-squares, correlations, t-tests, and analyses of variance. If these statistics are not familiar to you, seek consultation to ensure that you select the right type of analysis for your data and interpret the findings appropriately.

The most common statistical terms include: mean – the mean score represents a numerical average for a set of responses. Standard deviation – the standard deviation represents the distribution of the responses around the mean.

Many statistical analyses use the mean as a standard measure of the center of the distribution of the data. But unusual values, called outliers, affect the median less than they affect the mean.
Interpreting test statistics for any combination of sample sizes and number of predictor variables, a statistical test will produce a predicted distribution for the test statistic. This shows the most likely range of values that will occur if your data follows the null hypothesis of the statistical test.

Add a regression fit line to the scatterplot to model relationships in your data. )if a model fits well, you can use the regression equation for that model to describe your data.
Another way of looking at standard deviation is by plotting the distribution as a histogram of responses. A distribution with a low sd would display as a tall narrow shape, while a large sd would be indicated by a wider shape.
Descriptive statistics and interpreting statistics descriptive statistics are useful for describing the basic features of data, for example, the summary statistics for the scale variables and measures of the data. In a research study with large data, these statistics may help us to manage the data and present it in a summary table.
