how to find assumed mean in ungrouped data?

Dear Student,
Please find below the solution to the asked query:

Example:  Let us take the case of temperatures recorded in centigrade for 10 days for a place.Let they be 25 °C,30°C,31°C,34°C,32°C,31°C,30°C,28°C,30°C,31°CLet  30  be the assumed mean.Note: Any score can be assumed to be the mean but we normally take the score which is in the middle part of the distribution as assumed mean.The Deviation D  Score- Assumed mean is calculated for each of the score.Average mean=A+fDNumber of scores

Hence:Average mean=30+210=30.2 °C
