Why could the mean of the data set below be misleading?
ages of teachers: 29, 38, 39, 26, 29, 29, 39, 77, 38, 29

Answer :

  • The mean of teachers ages are 37.30.

Step-by-step explanation:

Given that

  • Ages of teachers:

            29, 38, 39, 26, 29, 29, 39, 77, 38, 29

To find

  • The Mean of teachers ages ?

So, according  to the question

We have,

  • Ages of teachers:
  •            
  • 29, 38, 39, 26, 29, 29, 39, 77, 38, 29

So, we know that

  • The mean of any given data

               mean = [tex]\frac{sum\;of\;\;data}{number\;of\;data}[/tex]

  • So, the sum of the teachers ages

                   ∑ Ta =  29+ 38+ 39+ 26+ 29+ 29+ 39+ 77+ 38+ 29

                   ∑ Ta =  373

  • The number of teachers

                     Tn =  10        

Now, The Mean of teachers ages

                     Tm =  [tex]\frac{sum\;of\;the\;teachers\;ages}{number\;of\;teachers}[/tex]

                     Tm =  [tex]\frac{T_a}{T_n}[/tex]

                            =  [tex]\frac{373}{10}[/tex]

                     Tm  =  37.30

Answer:

  • The mean of teachers ages are 37.30.
