Normal standard detion true is-: (A) Mean = Median, (B) Mean > Median, (C) Median > Mean, (D) Mode > Mean
Answer is A. Repeated question the standard detion (SD, also represented by the Greek letter sigma s or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
