The frequency distribution of the adverse reactions of a drug as a part of a treatment is provided.

The relative frequency of a class interval in a grouped frequency distribution is obtained using the given formula:

$\text{Relative}\text{frequency}\text{of}\text{a}\text{class}\text{interval}=\frac{\text{Frequency}\text{of}\text{a}\text{class}\text{interval}}{\text{Sum}\text{of}\text{all}\text{frequencies}}脳100\%$

The table below shows the frequencies of different adverse reactions:

The sum of all frequencies is shown below:

$$\begin{gathered} \text{Sum}\text{of}\text{all}\text{frequencies}=57+21+60+51+53 \\ =242 \end{gathered}$$

Using the formula mentioned above, the relative frequencies for the different categories are calculated as shown below:

$$\begin{gathered} \text{Relative}{\text{freq}}_1=\frac{57}{242}脳100\% \\ =23.55\% \\ \text{Relative}{\text{freq}}_2=\frac{21}{242}脳100\% \\ =8.68\% \end{gathered}$$

$$\begin{gathered} \text{Relative}{\text{freq}}_3=\frac{60}{242}脳100\% \\ =24.79\% \\ \text{Relative}{\text{freq}}_4=\frac{51}{242}脳100\% \\ =21.07\% \end{gathered}$$

$$\begin{gathered} \text{Relative}{\text{freq}}_5=\frac{53}{242}脳100\% \\ =21.9\% \end{gathered}$$

It can be observed that the highest relative frequency,equal to 224.79%, is not very high as compared to the other frequencies.

Therefore, there is not one particular adverse reaction that appears to occur much more frequently than others.
