Find the range, mode, median and mean of the data set


A TV watching time survey was conducted in the class. Here we have frequency table of TV watching time in hours per day:
\begin{array}{|c|c|c|c|c|c|c|} \hline    \text{TV time} & 0 & 1 & 2 & 3 & 4 & 5 \\\hline  \text{Frequency} & 2 & 5 & 6 & 5 & 4 & 2 \\\hline \end{array}
Using this frequency table make tasks below:
a) find the number of children in this class b) find the range of this data set c) find the mode of this data set d) find the median of this data set e) find the mean of this data set

a) [tex]2+5+6+5+4+2=24[/tex]
b) [tex]\text{Range}=5-0=5[/tex]
c) [tex]\text{Mode}=2[/tex]
d) [tex]\text{Median}=2[/tex]
e) [tex]\bar{x}=\frac{0 \cdot 2+1 \cdot 5+2 \cdot 6+3 \cdot 5+4 \cdot 4+5 \cdot 2}{24}=\frac{58}{24}\approx 2.4[/tex]
