Qualitative Data Quantitative Analysis (1694 words) |
 | Scholars of social change have lots of longitudinal quantitative data available (the Gallup poll for the last 50 years, the Bureau of Labor Statistics surveys for the last couple of decades, baseball statistics for over a hundred years, to name a few well-studied data sets), but longitudinal text data are produced naturally all the time. |
| In fact, in the phrases "qualitative data analysis" and "quantitative data analysis," it is impossible to tell if the adjectives "qualitative" and "quantitative" modify the simple noun "data" or the compound noun "data analysis." It turns out, of course, that both QDA phrases get used in both ways. |
| The qualitative data (artifacts, speeches, ethnographies, TV ads) have to be turned first into a matrix, where the rows are units of analysis (artifacts, speeches, cultures, TV ads), the columns are variables, and the cells are values for each unit of analysis on each variable. |
| Mapping Quantitative Data (3809 words) |
| Area or polygon data may be measured for a variety of natural areas such as woodlots or forest stands or for administrative areas such as provinces, counties, townships, or census tracts. |
| For example, if most of the data values are concentrated at the low end of the distribution but some values are spread out over a wide range, we can adjust the class intervals by using narrow class intervals where we have high frequencies of observation and using wider class intervals where there are few observations. |
| Proportional symbols could be used to represent interval or ratio scale data with the size of the symbol being proportional to the magnitude of the data value. |
