Anda dapat menghapus nilai data yang ditampilkan menggunakan dan dengan menekan (CL). Menghapus nilai data menyebabkan semua nilai yang mengikutinya tergeser naik. fx-82MS/fx-85MS/fx-300MS/fx-350MS: Anda juga dapat memasukkan beberapa entri data yang sama menggunakan (;). Untuk memasukkan data 110 kali contohnya, tekan 110 (;) 10 . Setiap Anda menekan untuk mendaftarkan input, jumlah data yang tersimpan sampai saat itu akan ditampilkan di display (nilai n). Next, use the regression formula to estimate atmospheric pressure at -5°C and temperature at 1000 hPa. Finally, calculate the coefficient of determination (r 2) and sample covariance ( ∑ xy - n∙ x -∙ y - n - 1). Next, use the regression formula to estimate the values for y ˆ (estimated value of y) for x i = 16 and x ˆ (estimated value of x) for y i = 20.

Since these calculators are products used as educational tools for long periods of time, materials that ensure robust key durability and prevent wear or fading of key markings are used to ensure product quality. You can also input multiple entries of the same data using (;). To input the data "20 and 30" five times, for example, press 20 30 (;) 5 . You can delete a data value displayed using and by pressing (CL). Deleting a data value causes all values following it to be shifted up.

A comprehensive set of advanced functions unique to CASIO scientific calculators

Contoh: Untuk menghitung s x, σ x, x -, n, Σ x, dan Σ x 2 dengan data berikut : 55, 54, 51, 55, 53, 53, 54, 52 fx-220 PLUS: Anda juga dapat memasukkan beberapa entri data yang sama menggunakan (;). Untuk memasukkan data 110 kali contohnya, tekan 110 (;) 10 . fx-220 PLUS: You can also input multiple entries of the same data using (;). To input the data 110 ten times, for example, press 110 (;) 10 . You can then edit the displayed data, if you want. Input the new value and then press the key to replace the old value with the new one. This also means that if you want to perform some other operation (calculation, recall of statistical calculation results, etc.), you should always press the key first to exit data display.

High product quality prevents key malfunction due to drop impact if a calculator falls to the floor from a desk in the classroom or display (LCD) or key breakage if a calculator is accidentally crushed in a schoolbag. fx-82MS/fx-85MS/fx-300MS/fx-350MS: You can also input multiple entries of the same data using (;). To input the data 110 ten times, for example, press 110 (;) 10 . Saat memasukkan data atau setelah input data selesai, Anda dapat menggunakan tombol dan untuk menyusuri kembali data yang telah Anda input. Jika Anda memasukkan beberapa entri dari data yang sama menggunakan (;) (atau (;) pada fx-220 PLUS) untuk menentukan frekuensi data (jumlah item data) seperti diuraikan di atas, menyusuri data akan memperlihatkan item data dan juga layar terpisah untuk frekuensi data (Freq). Do not use variables A through F, X, or Y to store data when performing statistical calculations. These variables are used for statistical calculation temporary memory, so any data you may have assigned to them may be replaced by other values during statistical calculations. Pressing the key instead of after changing a value on the display registers the value you input as a new data item, and leaves the old value as it is.Since 1935, the scientific community has used almost exclusively the thermochemical conventional definition of
