R Programming: Get the statistical summary and nature of the data of a given data frame

R Programming: Data frame Exercise-4 with Solution

Write a R program to get the statistical summary and nature of the data of a given data frame.

Sample Solution :

R Programming Code :

exam_data = data.frame(
name = c('Anastasia', 'Dima', 'Katherine', 'James', 'Emily', 'Michael', 'Matthew', 'Laura', 'Kevin', 'Jonas'),
score = c(12.5, 9, 16.5, 12, 9, 20, 14.5, 13.5, 8, 19),
attempts = c(1, 3, 2, 3, 2, 3, 1, 1, 2, 1),
qualify = c('yes', 'no', 'yes', 'no', 'no', 'yes', 'yes', 'no', 'no', 'yes')
)
print("Original dataframe:")
print(exam_data)
print("Statistical summary and nature of the data of the said dataframe:")
print(summary(exam_data))

Sample Output:

[1] "Original dataframe:"
        name score attempts qualify
1  Anastasia  12.5        1     yes
2       Dima   9.0        3      no
3  Katherine  16.5        2     yes
4      James  12.0        3      no
5      Emily   9.0        2      no
6    Michael  20.0        3     yes
7    Matthew  14.5        1     yes
8      Laura  13.5        1      no
9      Kevin   8.0        2      no
10     Jonas  19.0        1     yes
[1] "Statistical summary and nature of the data of the said dataframe:"
        name       score          attempts    qualify
 Anastasia:1   Min.   : 8.00   Min.   :1.00   no :5  
 Dima     :1   1st Qu.: 9.75   1st Qu.:1.00   yes:5  
 Emily    :1   Median :13.00   Median :2.00          
 James    :1   Mean   :13.40   Mean   :1.90          
 Jonas    :1   3rd Qu.:16.00   3rd Qu.:2.75          
 Katherine:1   Max.   :20.00   Max.   :3.00          
 (Other)  :4
