《You and I》是2NE1演唱的一首歌曲，歌詞如下所示：
女：
You and I, know we're stars
One and two, know we rules the part
Go and get 'em boys
Check it out girls
男：
Ye who said you don't love your motherland
Should get up, all they really deserve
（Boom Shakalaka） is the beat I want to go up on stage
Even if you the harshest they should show respect
女：
Hot, look how I be lit up, hey, so tight like the south pole
Right in, not for rent, and if you play I take you up for flight
Trap game high as fk, just chill just don't need your pearl
I ain't a trap hoe, I ain't even got a trap hoe
男：
Yo, I ain't even got a problem with my money green
But I ain't tryna flex on your haters when I leave
I ain't tryna be the best at being rude
But I ain't tryna be the worst at being nice
I ain't tryna flex on nobody when I leave
But I ain't tryna be the best at being nice
女：
You and I, should we run it?
Should we take it slow?
I ain't tryna be your bae, I ain't tryna play it low
You and I, we should ride it out
No rush no drama, it ain't for us
Don't tryna get your rocks off on my neck boy oh boy oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh boy boy boy boy boy boy boy boy boy boy boy
男：
Chickenhead (yoo hoo), too cold to let it get that far (woah)
Just another reason why they love me so much (woah)
Yeah yeah yeah yeah yeah, so if you think you got game better make it tighter
Come on girls come on boys let's get it started
女：
Hot, look how I be lit up, hey, so tight like the south pole (it be hot when you leave)
Right in, not for rent (that is right) and if you play I take you up for flight (ooh la la)
Trap game high as fk, just chill just don't need your pearl (and your pearl)
I ain't a trap hoe (na na na) and you just like an open door (nooo)
Yeah yeah yeah yeah yeah, why? I am feeling real strong
Boys will be boys, now make me want to throw down like a video game that we in, watch my trigger discipline you might think I gone break a bad habit you in for the shock給定一組數據，請回答以下問題：
問題：這組數據的平均數是多少？中位數是多少？眾數是多少？是否存在極端值？如果有，是哪兩個？請說明理由。
答案：這組數據的平均數為（3+4+5+6+7）/5 = 5，中位數為5，眾數為3和4。存在極端值，極端值是6和7。理由如下：這組數據共有5個數據，按照從小到大的順序排列為3、4、5、6、7。由於數據個數為偶數，所以中位數為中間兩個數的平均數，即（5+6）/2 = 5。眾數為一組數據中出現次數最多的數據，所以眾數為3和4。由於數據中最大值為7，所以存在極端值，極端值是6和7。
