find mean and median of the following heights of girls 62,64,59,61,63​

Answer 1

Solution:-

━━━━━━━━━━━━━━━━━━━━━━━━━━

MEAN:-

$\dashrightarrow$Here, the question has given us the heights of girls that are:- 62,64,59,61,63. Now the question has asked us to find the mean height. So, we simply have to apply the formula of mean and solve to get the mean height of u students.

ANSWER:-

☯ The mean height of the girls is 62.

GIVEN:-

⟶ Height of girls (data) = 62, 64, 59, 61, 63

TO FIND:-

⇾ Mean height = ?

FORMULA:-

$\to \bf{Mean = \dfrac{Sum \: of \: all\:observations}{Number \: of \: observations}}$

SOLVING BY APPLYING THE FORMULA:-

↬ Mean = Sum of total / Number of terms

↬ No. of terms = 5

↬ Mean = 62 + 64 + 59 + 61 + 63

↬ Mean = 309 / 5

↬ Mean = 309 / 5 = 61.8

↬ Mean = 61.8 [Round off to the nearest whole]

↬ Mean = 62

Hence, we got the answer. The mean height of the girls is 62.

MEDIAN:-

⇝ Here, the question has asked us to find the median of the data that is 62, 64, 59, 61, 63. So, to find the median we will apply the formula of median. Arrange the data in ascending or descending order. There are 5 terms in the data as 5 is an odd number we will apply (n+1)/2th formula.

ANSWER:-

» The median is 62.

GIVEN:-

✪ Data = 62, 64, 59, 61, 63

TO FIND:-

➤ Median of data = ?

FORMULA USED:-

• Median = (n+1)/2th

SOLVING STEP BY STEP:-

✪ Data = 62, 64, 59, 61, 63

⟶ Arrange in ascending = 59, 61, 62, 63, 64

⟶ No. of observations (n) = 5

⟶ Median = (5+1)/2th

⟶ Median = (6/2)th

⟶ Median = 3th term

⟶ Median = 62 [As 62 is the 4th term]

Thus, we got the median. The 3th term that is 62 is the median of the data.

KNOW MORE:-

• The formula used above is used when data is not given in form of a table.
• The Formula of median when the data is given in tables or frequencies.
• If n is odd then (n+1)/2th term will be median.
• If n is even then average of middle two terms which are n/2th term and (n/2)+1th term is median.
