Find the values of the mode when median is given to be 5 and mean is 7.

Reil [10]

Answer:

Mode = 1

Step-by-step explanation:

Relation between the Central Measures of Tendency

Mean, Median, and Mode are commonly referred to as the Central Measures of Tendency
The formula between the three is given by :
⇒ Mode = 3Median - 2Mean or Mode + 2Mean = 3Median

Solving

We know that :

Median = 5
Mean = 7

Therefore,

Mode = 3(5) - 2(7)
Mode = 15 - 14
Mode = 1
