Multimodal or unimodal

The weights (in kg) of 13 students of a class are 37,39,33,32,41,33,37,45,43,39, 33,40,39

Find the mode & media of this data (F). Is there more than one mode?

Final Answer:

m₁ =  33 kg
m₂ =  39 kg
m =  39 kg

Step-by-step explanation:

$$\begin{gathered} data:37,39,33,32,41,33,37,45,43,39,33,40,39 \\ sort:32,33,33,33,37,37,39,39,39,40,41,43,45 \\ mod{e}_1: \\ count(33kg)=count(39kg)=3\dots max \\ {m}_1=33=33\text{kg} \end{gathered}$$

$$\begin{gathered} mod{e}_2: \\ {m}_2=39=39\text{kg} \end{gathered}$$

$$\begin{gathered} median \\ median=sorted(15/2)=sorted(7) \\ m=39=39\text{kg} \end{gathered}$$
