he term observed frequency refers to . the frequencies found in the sample data the frequencies found in the population being examined the frequencies computed from the null hypothesis the frequencies that are hypothesized for the population being examined

(A)the frequencies found in the sample data.

Step-by-step explanation:

In a given experiment or trial, the frequency of the item under consideration is referred to as the observed frequency. The experiment is carried out on only a sample of the population.

Observed frequencies are the frequencies actually found in the data while expected frequencies are calculated from the observations given assuming the null hypothesis to be true.

Therefore, the term observed frequency refers to the frequencies found in the sample data.
