ヒント

• これらの数式に慣れたら、「数式の挿入」手順をスキップして、次の関数を直接入力できます。
  • 平均— "=AVERAGE(セル範囲)" → 例: "=AVERAGE(D4:D13)"
  • 標準偏差— "=STDEV(セル範囲)" → 例: "=STDEV(D4:D13)"
  • この方法を使用する場合は、等号を忘れないようにしてください。等号を入力すると、セルに入力しているものが数式であることを Excel に伝えることができます。
• 以前のバージョンの Excel を使用する場合は、ツールバーの「数式ウィザード」ボタンをクリックして同じ操作を完了できます。 [統計] をクリックして [平均] を選択するか、[統計] をクリックして [標準偏差] を選択します。
