# US GDP

Consider the following dataset , which contsins the domestic US gross in millions of the top grossing movie over the last 5 years. 300,452,513,550,780

I. Find the Mean of the Dataset
II. Find the Squared deviation of the second observation from the mean
III. Find the squared deviation of X2 from the Mean

m =  519
d =  4489
x2 =  30392

### Step-by-step explanation:

$m=\left(300+452+513+550+780\right)\mathrm{/}5=519$
$d=\left(452-m{\right)}^{2}=\left(452-519{\right)}^{2}=4489$
${x}_{2}=\left(\left(300-m{\right)}^{2}+\left(452-m{\right)}^{2}+\left(513-m{\right)}^{2}+\left(550-m{\right)}^{2}+\left(780-m{\right)}^{2}\right)\mathrm{/}\left(5-1\right)=\left(\left(300-519{\right)}^{2}+\left(452-519{\right)}^{2}+\left(513-519{\right)}^{2}+\left(550-519{\right)}^{2}+\left(780-519{\right)}^{2}\right)\mathrm{/}\left(5-1\right)=30392$
