Answer 1

Explanation:

Mean, Median,mode

`\boxed{Mean = (Sum \ of \ all \ data)/(number \ of data)}`

`\sf = (234 + 247 + 236+212+248+243+176+195)/(8)\\\\= (1791)/(8)\\\\= 223.875`

Median:

Arrange the numbers in ascending order.

176 , 195 , 212 , 234 , 236 , 243 , 247, 248

Number of data is even. So, median will be the average of 234 and 236

Median = average of the middle two terms.

`\sf = (234+236)/(2)\\\\ =(470)/(2)\\\\= 235`

Mode is the data which is occurring more number of times.

Range = maximum - minimum

= 248 - 176

= 72
