[{'content': 'Mode is defined as - \nSelect and explain. \nA. Most frequent value, B. Middle value, C. Minimum value, D. None', 'role': 'user'}, {'content': 'Answer: A \nExplanation: The mode\n\nThe mode is the value that occurs the most frequently in a data set.\nFor example the diastolic BP of 10 individuals 75, 71, 73, 84, 81, 75, 79, 75, 80, 90\nThe most frequently occurring value is 75, and therefore the mode.\nIf there are 2 most frequent value in the distribution, i.e., two modes → Bimodol distribution. \nFor example: For\xa0Hodgkin\'s lymphoma, there are two age groups around which most of the cases occur.\n\nAdvantage\n\nEasy to understand and is not affected by extreme items (skewed deviation).\nThe concept of mode makes sense for nominal data (i.e., not consisting numerical values). For example, taking a sample of korean family names, one might find "Kim" occurs more often than any other name. Then "Kim" might be called the mode of the sample.\n\nDisadvantage\n\nExact location is often uncertain and is often not clearly defined.', 'role': 'assistant'}]
