Question

Make a frequency distribution table using 28 as the class interval and start first class from 62 onwards

106	107	76		82	109	107	115	93	187	95
148	92	86	70	126	64	130	129	139	119
111	186	84	99	113	204	111	141	136	123
100	110	78	185	162	178	140	152	173	146
98	90	107	181	131	75	184	104	110	80

Answer 1

First, I copied the table of numbers to an MS Word table.

Them, I converted to table to text and eliminated the blank entries.

106

107

76

82

. . .

Then, I sorted the table:

64

70

75

76

78

80

. . .

Now, I can group or count the observations between 62, 90, 118, … 230 [note: intervals of 28].

  62-89:        64,    70,       75,      76,      78,    80,     82,     84,     86

 90-117:        90,    92,       93,      95,     98,     99,   100,   104,   106,   107,   107,   107,   109,   110,   110,   111,   111,   113,   115

118-145:     119,    123,   126,   129,   130,   131,   136,   139,   140,   141

146-173:     146,    148,   152,   162,   173

174-201:     178,    181,   184,   185,   186,   187

202-229:      204 

Now, make it a frequency table:

  62-89:        9

 90-117:      19

118-145:    10

146-173:      5

174-201:       6

202-229:       1

and plot it:
