Measures of Central Tendency Arithmetic Mean : Average of all values (sum divided by count). Geometric Mean : nth root of the product of values (used for growth rates). Harmonic Mean : Reciprocal of the average of reciprocals (used for rates like speed). Median : Middle value when data is ordered. Quartiles : Values dividing data into four equal parts (Q1=25th, Q2=50th=median, Q3=75th percentile). Mode : Most frequent value. Measures of Dispersion Range : Difference between maximum and minimum values. Quartile Deviation : Half the interquartile range (Q3 - Q1)/2. Mean Deviation : Average absolute deviation from the mean. Variance : Average squared deviation from the mean. Standard Deviation : Square root of variance (spread in original units). Coefficient of Variation : (Standard Deviation / Mean) × 100% (relative variability). Data Distribution Shapes Symmetric : Balanced, mean = median = mode (e.g., normal distribution). Skewed Right : Longer right tail, mean > median > mode. S...
Introduction to Pedagogical Approaches and Teaching Styles/Techniques (Teaching Practice B.Ed Hons Level Course)
Brief Introduction to Pedagogical Approaches and Teaching Styles/Techniques Pedagogy involves the specific technique, art and science of teaching. Pedagogy is a process of infusing/injecting knowledge into the minds of learners. It includes the theories, methods, and practices used to help students learn. Similarly, pedagogical approaches and teaching styles or techniques are frameworks and strategies that teachers use to meet the different needs of learners, promote engagement, and reach educational goals. For both, teachers and learners, pedagogy covers all the important aspects including knowledge acquisition, knowledge developing and knowledge creation as Suggested by UNESCO's Framework 2030 . These approaches vary based on their philosophical foundations, specific learner contexts, and desired outcomes. Below is an overview of major pedagogical approaches, teaching styles, techniques, and the importance of adapting to context. Overview of Major Pedagogical Approaches Pe...
