Question 1

Which set of data does not have a mode?

(A) 1, 2, 5, 6, 8
(B) 1, 3, 5, 5, 6
(D) 1, 1, 1, 2, 2
(C) 1, 5, 5, 5, 5

Question 2

A, because it does not repeat any numbers

Question 3

$\huge\text{Hey there!}$

$\huge\textbf{Question reads....}$

$\textbf{Which set of data does not have a mode?}$

$\huge\textbf{The choices that you have provided:}$

$\textbf{(A) 1, 2, 5, 6, 8}$

$\textbf{(B) 1, 3, 5, 5, 6}$

$\textbf{(C) 1, 5, 5, 5, 5}$

$\textbf{(D) 1, 1, 1, 2, 2}$

$\huge\textbf{Okay, so let's get the understanding}\\\\\huge\textbf{of the word mode is:}$

$\large\textbf{The best way to understand what \boxed{\bf mode} it is known as}\\\\\large\textbf{the number you see MORE THAN once. }$

$\huge\textbf{Now that we got that information out of}\\\\\huge\textbf{the way, we can answer your question by}\\\\\huge\textbf{doing process of elimination.}$

$\huge\textsf{Option A.}$

$\textbf{1, 2, 5, 6, 8}$

$\large\textbf{None of the numbers r.e.p.e.a.t so this cann be your}\\\\\large\textbf{answer.}$

$\huge\textsf{Option B.}$

$\textbf{ 1, 3, 5, 5, 6}$

$\large\textbf{1}\rightarrow\large\textbf{ is r.e.p.e.a.t.e.d once}\\\large\textbf{3}\rightarrow\large\textbf{ is r.e.p.e.a.t.e.d once}\\\large\textbf{5}\rightarrow\large\textbf{is r.e.p.e.a.t.e.d twice}\\\large\textbf{6}\rightarrow\large\textbf{is r.e.p.e.a.t.e.d once}$

$\large\textbf{Just because majority of your numbers r.e.p.e.a.t.e.d}\\\\\large\textbf{once that doesn't mean it does have a mode rarely.}\\\\\\\\\\\large\textbf{So, Option B. isn't your answer because it has a mode.}$

$\huge\textsf{Option C.}$

$\textbf{ 1, 5, 5, 5, 5}$

$\large\textbf{1}\rightarrow\large\textbf{is r.e.p.e.a.t.e.d once}\\\large\textbf{5}\rightarrow\large\textbf{is r.e.p.e.a.t.e.d four times}$

$\large\textbf{Option C. isn't your answer because it has a mode.}$

$\huge\textsf{Option D. }$

$\textbf{1, 1, 1, 2, 2}$

$\large\textbf{1}\rightarrow\large\textbf{is r.e.p.e.a.t.e.d three times}\\\large\textbf{2}\rightarrow\large\textbf{is r.e.p.e.a.t.e.d twice}$

$\large\textbf{Just because we have like two modes, it still doesn't mean}\\\large\textbf{you don't have a mode. It 's kind of cool that you have more}\\\large\textbf{than once mode.}$
