We will experiment with Latent Semantic Analysis (LSA) technique in topic modeling. Qualitative Data Analysis is outlined as the method of consistently looking and composing the interview records, observation notes, or completely different non-textual materials that the investigator accumulates to increase the understanding of an event. TDA provides a general framework to analyze such data in a manner that is insensitive to the particular metric chosen and provides The unit of observation should not be confused with the unit of analysis.A study may have a differing unit of observation and unit of analysis: for example, in community research, the research design may collect data at the individual level of observation but the level of analysis might be at the neighborhood level, drawing conclusions on Data are collected using techniques such as measurement, observation, query, or analysis, and typically represented as numbers or characters which may be further processed. Description of the example data. Also at the top of the output we see that all 200 observations in our data set were used in the analysis (fewer observations would have been used if any of our variables had missing values). Field data are data that are collected in an uncontrolled in-situ environment. The TRMM rainfall analysis was created using data from two instruments on TRMM: TRMM's Microwave Imager (TMI) and Precipitation Radar (PR). Qualitative Data Analysis (QDA) is the range of processes and procedures used on the qualitative data that have been collected to transform them into some form of explanation, understanding or interpretation of the people and situations that are being investigated.
