Step-by-step explanation:

$Mean = \frac{Sum \: \: of \: observations}{No. \: \: of \: \: observations}$

$Mean = \frac{87 + 39 + 45 + 67 + 25 + 39 + 78}{7} \\ \\ = \frac{380}{7} \\ \\ = 54.28$

---------------------------------------------

${Median}$

Arranging data in ascending order

25 < 39 = 39 < 45 < 67 < 78 < 87

Cancelling 1-1 terms form both sides, we get median as 45

---------------------------------------------

${Mode}$

Mode is the value or values in the data set that occur most frequently.

∴ mode is 39
