Answer :

mean = 4

median = 3

mode = 3

Mean = Sum of all observations

number of observations

median refers to the value which lies in the middle of the data( when arranged in an increasing or decreasing order)

The mode of a set of observations is the observation that occurs most often.

REQUIRED MEAN, MEDIAN AND MODE ARE 4, 3 & 3 RESPECTIVELY

⠀⠀⠀

\begin{gathered}:\implies\sf Mean = \bigg(\dfrac{2 + 7 + 0 + 3 + 5 + 0 + 9 + 3 + 8 + 3}{10} \bigg) \\\\\\:\implies\sf Mean = \cancel\dfrac{40}{10} \\\\\\:\implies{\underline{\boxed{\frak{\pink{Mean = 4 \: goals}}}}}\;\bigstar\end{gathered}

\therefore{\underline{\sf{Required\; mean \; is \; \bf{4}.}}}

⠀⠀⠀

Scores = 0, 0, 2, 3, 3, 3, 5, 7, 8, 9 (in increasing order)

Number of observation, n = 10.

⠀⠀⠀

Therefore,

⠀⠀⠀

\star\;\boxed{\sf{\purple{Median = \dfrac{\bigg(\dfrac{n}{2}\bigg)^{th}\; observation \: + \; \bigg(\dfrac{n}{2} + 1 \bigg)^{th} \; observation}{2}}}}

⠀⠀⠀

Therefore,

⠀⠀⠀

\begin{gathered}:\implies\sf Median = \dfrac{\bigg(\dfrac{10}{2} \bigg)^{th} \: observation \; + \; \bigg(\dfrac{10}{2} + 1 \bigg)^{th}\; observation}{2} \\\\:\implies\sf Median = \bigg(\dfrac{5^{th} \; observation + 6^{th} \; observation}{2} \bigg) \\\\:\implies\sf Median = \bigg(\dfrac{3 + 3}{2}\bigg) \\\\:\implies\sf Median = \bigg(\dfrac{6}{2} \bigg) \\\\\\:\implies{\underline{\boxed{\frak{\purple{ Median = 3}}}}}\;\bigstar\end{gathered}

⠀⠀⠀

\therefore{\underline{\sf{Required\; median \; is \: \bf{3 }.}}}

Mode is the most appearing value.⠀

Therefore, 3 is the most appearing value in the given observation. ⠀

⠀⠀⠀

\therefore{\underline{\sf{Required\; mode \;is\; \bf{3 }.}}}
