On August, 6, 2019, we had a lecture about quantitative research with David Christian. The lecture was about the details of quantitative research and the most significant procedures included in.  So quantitative research must include confidentiality, title, create questions, and how can you measure change or progress. All these things are considered as something critical in the quantitative research to complete your paper. this type of research can also be used to inform instructional decisions measuring the effectiveness of school climate. Thus, the importance of such kind of research is that to inform us what percent of any group responded to a particular feature or intervention as compared to groups that did not receive the particular feature or intervention. Again it is something that is in relation to the percentage and statistical analysis. The most important terms that I learned through this lecture is that the null analysis, correlation, Pearson r, T-test, and ANOVA. All these terms are considered as critical in any quantitative analysis to achieve the required results. For me, the lecture was very useful and interesting since I learned many things about what is called " quantitative research''. I hope that all what I learned through this lecture would be delivered to my students to apply it in our researches. I am pretty sure that this lecture will be very critical to our senior students who have a research paper project. My impression about the lecture is that it was not boring and I liked the way it is delivered and this is my main concern. With tow-day lecture we dealt with a lot of information in regard to the topic that needs more than two lectures to be covered but that happened because the lectures were intensive.
