FAQs (Frequently Asked Questions)
Q1.What do you Mean by Median, Mean, and Mode?
Ans: Mean:- It refers to average. Mean is the average of a given set of data. We can calculate by dividing the sum of all values by several values.
Mean = (n1 + n2 +........n10)/10.
Median:- Simply, the middle term of the set is known as the set’s median. If it has an even number of terms in the set, the average of two middle terms is the median.
Mode:- The highest repetitive term of the set is called the mode of the set.
Q2. Explain the Relationship Between Mean, Median, and Mode?
Ans: As these three are statistical measures, all are interrelated but can't say dependent all the time. The relation can be understood easily by plotting graphs. Apart from that, after several observations, it is clear that the difference between mean and mode is equal to the thrice of the difference between mean and median. It can be represented as,
Mean – Mode = 3 (Mean – Median).
We will also get a symmetrical curve when we plot the graph while showing the relation between them. It also considers frequency distribution on the other side.
