Mean, Median, Mode, and Range are important measures of central tendency and data analysis. Mean (Average): The sum of all values divided by the total number of values. 👉 Formula: Mean = (Sum of all observations) / (Total number of observations) Median: The middle value when data is arranged in ascending or descending order. 👉 If the number of observations is even, Median = (Middle two values) / 2 Mode: The number that appears most frequently in a data set. 👉 A set can have one mode, more than one mode, or no mode. Range: The difference between the highest and lowest values in a data set. 👉 Formula: Range = Highest value − Lowest value These concepts help in analyzing data trends and are frequently asked in HEC, USAT, HAT, LAT, NTS, ETEA, and other competitive exams. --- 📊 Hashtags: #Mean #Median #Mode #Range #CentralTendency #DataAnalysis #MathPreparation #HEC #USAT #HAT #LAT #NTS #ETEA #CompetitiveExams #MathConcepts #StudySmart #ExamPreparation
