Setelah menghitung R, K, dan i, kita dapat membuat tabel distribusi frekuensi.
2. Buat tabel distribusi frekuensi dengan terlebih dahulu dihitung nilai range (R), jumlah kelas (K) (dengan rumus sturgess) dan Interval kelas (i).
To calculate the mean, median, and mode of the ungrouped data provided, follow these steps:
a. Calculate the Mean:
Add up all the values and divide by the total number of values.
Sum of all values = 6474
Number of values = 47
Mean = Sum of all values / Number of values = 6474 / 47 = 137.7
b. Calculate the Median:
Arrange the data in ascending order: 116, 119, 123, 125, 126, 127, 128, 132, 135, 135, 135, 136, 138, 138, 140, 140, 142, 142, 143, 144, 144, 145, 145, 145, 146, 146, 146, 147, 147, 149, 150, 150, 152, 153, 153, 154, 156, 156, 157, 158, 161, 163, 164, 165, 166, 168, 173, 176
