How to Save a Life - The Script
Verse 1:
Sometimes I feel like I'm drowning
In a sea of my own creation
Trying to find my way back to the surface
But I'm too far down to navigate
Chorus:
How to save a life when you don't want to live?
How to wake up when you don't feel alive?
It's a battle you're fighting all by yourself
But you won't win if you give up control
Verse 2:
I know it's darkest before the light
And I know there's still time for a reset
But I'm tired of fighting on my own
I need someone to show me the way out
(Chorus)
Bridge:
You don't have to be alone in this fight
There's still time to turn it all around
You don't have to give up just yet
There's still hope, there's still hope out there
(Outro)
You're not alone, there are people who care

算術平均數是用於求一個數據的所有數據的平均數的，加權平均數通常用於多個數據項，每個數據項的數值大小和數量都不同的情況，用以反映每個數據項對最終結果的影響程度。中位數則用於將一組數據按大小排序後，處於中間位置的那個數值，通常用於反映一組數據的中間趨勢。眾數則用於表示一組數據中出現次數最多的數值，通常用於反映一組數據的集中趨勢。
因此，答案是B.算術平均數。希望這個答案可以幫到你。如果還有其他問題，歡迎繼續提問。
