Answer:
a.Mean, mode and median.
Step-by-step explanation:
Central tendency measures are mean, mode and median.
Mean: It is defined as the average value of the given data .
Mean =[tex]\frac{total \;sum\; of \;date}{Total\;number\; in\;data}[/tex]
Mode :The number which appear most times in the given set of data.
Median:It is defined the middle value of the given data.
Median for even number of terms in data
Median =[tex]\frac{\frac{n}{2}^{th} term+(\frac{n}{2}+1)^{th} term}{2}[/tex]
Median for odd number of terms in data set
Median=[tex]\frac{n+1}{2}^{th} term[/tex]
Mean=[tex]\frac{23+50+49+48+49+32+37+40+41+42+41+41+43}{13}[/tex]
Mean=41.2
Mode:41 appears 3 times which is most time repeat .
Therefore, Mode=41
23,32,37,40,41,41,41,42,43,48,49,49,50
Total number of terms are odd
Median =[tex]\frac{13+1}{2}^{th} term [/tex]
Median=[tex]\frac{14}{2}=7^{th}[/tex] term=41
Median=41
Answer: a : Mean, mode and median
