Standard deviation and Variance in animal breeding

Standard Deviation The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma) The formula is easy: it is the square root of the Variance. So now you ask, “What is the Variance?“ Variance The Variance is defined as: The average of the squared differences from the Mean. To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. #variance #StandardDeviation #Genetics #computationalBiology #statistics #breeding #CarnegieMellonUniversity #schoolOfComputerScience #Bioinformatics #undergraduate #systemsBiology #informatics #sequenceDatabases #sequenceAlignment #BLAST #genomics #tibees #studyWithMe #tibeesPhysics #biologyAndComputerScience #biology #coding #DNA #studyWithMeBiology #biologyStudy #learningPhysics #brilliantorg #biologyMajor #college #python #apBiology #reviseWithMe #scienceStudent
