Find the pattern of the data of Chi-square goodness-of-fit from two options.

Two options regarding the data for Chi-square goodness-of-fit tests are provided.
Chi-square goodness-of-fit test compares the proposed distribution with the empirical distribution. It is based on one random sample which has one categorical variable. This means that the data should have only one categorical variable of observed counts. The observed count can be represented either in one row or in one column.
Therefore, the chi-square goodness-of-fit data has one row or one column of observed counts but not both.
