Practical Research II SEMESTER 1 Mrs. Juvis Gem De la Cruz Ex. a. What is the level of engagement of the L1: QUANTITATIVE DATA ANALYSIS students in Pre-Calculus Blended class in terms of: 1.1 Behavioral engagement TOPIC OVERVIEW 1.2 Cognitive engagement and 1.3 Emotional Engagement A. QUANTITATIVE DATA ANALYSIS - We are only getting the level of a. Statistical Tools engagement of the students in the Pre Calculus Blended Learning class, therefore it is descriptive. (Is the level of A QUANTITATIVE DATA ANALYSIS engagement low or high?) - To answer that, we will use the mean to analyze the data gathering for this 1 STATISTICAL TOOLS research question. b. What is the academic performance of - These are tools that will help us in the students in Pre-Calculus Blended analyzing quantitative data in research Learning class? and decide whether to accept or reject - For example, what is the academic your null hypothesis. performance of the student? Is it - Whether we can say that there is a outstanding, beginner or what? significant difference or there is no - Mean will be used to analyze the data for significant difference. this. c. What is the mean number of conidia STATISTICAL TOOLS germinated on slide germination assay 1. Frequency and Percentage (descriptive with phomopsis…….. statistics) - Clue “what is the mean” - Used to indicate the frequency - We are describing the number of conidia - Ex. What is the profile of the participants germination. in terms of: 1.1 Gender 3.

What is the significance difference between the pre-test and post-test mean scores of the students? 5. One-Way Analysis of Variance (ANOVA) - This is used to determine whether there are any statistically significant differences between the means of two or more independent (unrelated) groups. Ex. a. Is there a significant difference in the level of engagement of the students in Pre-calculus blended learning when grouped according to th 6. PEARSON - R (relationship) - For numerical - Measure in strength and direction of association that exists between two variables measured atleast on an interval scale - Ratio is allowed but not categorical measurement (nominal and ordinal) Ex. a. Is there a significant relationship on the academic performance of students and their average daily time for reviewing? 7. Chi-Square (relationship) - This is a measure of the strength and direction of association that exists between two variables measured on nominal or ordinal scale. Ex. a. Is there a significant relationship between the academic performance of the students and their gender? PAGE 2 [Hans T. and Sean D.} YOUTH FOR ENVIRONMENT IN SCHOOLS ORGANIZATION
