Question

Are the observed frequencies variables? What about the expected frequencies? Explain your answers.

Short answer

Yes. The observed frequencies are the frequencies which falls under the classification of characteristic variable. Observed frequencies are almost equal to the expected frequencies. So, each observed frequency is roughly equal to its corresponding expected frequency.

Step-by-step solution

Step 1. Given information

We need to explain whether the observed frequencies are variables and also need to give the definition for the expected frequencies.

Step 2. A brief explanation about the observed and the expected frequencies:

Yes. The observed frequencies are the frequencies which falls under the classification of characteristic variable. Observed frequencies are almost equal to the expected frequencies. So, each observed frequency is roughly equal to its corresponding expected frequency.
