Introduction to quantitative analysis

Quantitative Analysis
Usefulness
The qualitative research by Johnson seeks to assess how teachers’ perceptions over Professional Learning Communities (PLC) interact with implementation of accountability reforms. The research is set on the background of increasing need for accountability in education management. It is therefore the premise of Johnson’s research that the teachers’ perceptions on PLC have a relevant relation with the instituted reforms (Johnson, 2011).
The research targets to give insights on the instituted reforms to the New Jersey education managers and to the overall national education taskforce on quality of teaching and learning. The research by Johnson’s 2011 will also facilitate in managing and implementing the reform efforts driven by call for accountability. The reform efforts come about owing to a change in guard over the previously independent school district currently being controlled at the federal and state level (Johnson, 2011)
Variables
Independent variable is the content of Professional Learning Community (PLC). The Dependent variables is the Perceptions of Educators that comprises of; Data driven decisions; Evaluation; Research-based practices; Learning outcome; Collaboration, quality of teaching, equity, and family involvement.
In the notation Y=f(X) +E, Y is the Perceptions of Educators - (the dependent variable) comprising of the above mentioned components (Johnson, 2011). X is the component of the Professional Learning Community - (Independent variable) that influences the components of Perceptions of Educators (Johnson, 2011).
Errors
The research by Johnson relies on self-reported responses from the educators. This presents a chance for individual subjective attributes to set in the research and influence the results. The absence of objectivity in the responses may lead to misleading information. The data information obtained from the survey may also have no true mean owing to the varied subjective attributes incorporated in the data (Dietz. & Kalof., 2009).
