IEEE T GEOSCI REMOTE. The primary goal herein was to process the data obtained from geochemical, geostatistical, and remote sensing tools (in the form of stream sediment samples and satellite images) to identify metallic mineralization anomalies in the region. In their method, concentration data from a settling column experiment are converted to percentage removals at various times and depths. The mixed-methods procedure will follow Joanna Briggs Institute guidance for a convergent integrated approach.31 This involves transforming extracted data from quantitative papers (and quantitative aspects of mixed-methods papers) by qualitising (creating a textual description) quantitative findings. An introductory economics textbook describes More precisely, it is "the quantitative analysis of actual economic phenomena based on the concurrent development of theory and observation, related by appropriate methods of inference". 5. It is assumed that the variables. For a univariate data, the most popular methods are histogram, bar chart, frequency tables, box plot, or the stem and leaf plots.
