A sample of 30 3-5 year old the children were asked tp count out loud. The highest number of numbers that a child can count before making a mistak is recorded and shown below numnbers counted: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 number of children frequency: 0 0 0 2 2 0 3 1 2 5 0 1 1 4 5 4 (a)What number(s) did most 3-5 years old children count up to ? (b) What is the median number of numbers to which 3-5 years old can count ? (c) What is the median number to which 3-5 year old can count up? sum of x= n=? mean = ?
A sample of 30 3-5 year old the children were asked tp count out loud. The highest number of numbers
that a child can count before making a mistak is recorded and shown below
numnbers
counted: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
number of
children
frequency: 0 0 0 2 2 0 3 1 2 5 0 1 1 4 5 4
(a)What number(s) did most 3-5 years old children count up to ?
(b) What is the median number of numbers to which 3-5 years old can count ?
(c) What is the median number to which 3-5 year old can count up?
sum of x=
n=?
mean = ?
(d) what is the standard deviation for which the number of numbers for which 3-5 year old
can count up ?
sum(x square)=
(sum of x ) squared =
standard deviation =?
