A Explain the meaning of the following terms :

(i) variate

(ii) class size

(iii) classmark

(iv) class limits

(v) true class limits

(vi) frequency of a class

(vii) cumulative frequency of a class.

Answer:

(i) Variant: A particular value of a variable is called variate.

(ii) Class size: The difference between the actual upper limit and the actual lower limit of a class is

called its class size.

(iii) Classmark: The class mark of a class is the value midway between its actual lower limit and actual

upper limit.

(iv) Class limits: In the frequency table the class interval is called class limits.

(v) True class limits: In a continuous distribution, the class limits are called true or actual class limits.

(vi) Frequency of a class: The number of tally marks opposite to a variate is its frequency and it is

written in the next column opposite to tally marks of the variate.

(vii) Cumulative frequency of a class: The sum of the frequency of all previous classes and that particular

class is called the cumulative frequency of the class.

"guys welcome to lido q a video
i am vineet your leader tutor bringing
you this question
on your screen so this is
a very easy and straightforward question
so what does it say explain the meaning
of the following terms
so we are going to do just that
okay so the first one is
variate what is a variant
a variate is a particular value of a
variable
right a particular
value of a variable
is called a variate
right now what is class
size these are all very easy definitions
we all know this so class size is
the difference between the actual upper
limit and the actual lower limit of a
class
so this is
the difference
between
the actual upper limit
and actual lower limit
so this is class size
next would be
class mark what is a class mark
so plus mark is nothing but
it is the value midway between its
actually lower limit
and actual upper limit so
it is the value midway
exactly in between
the actual upper and lower limits
right now what are class
limits
again we'll have to draw a line
to bifurcate so
here it is okay now
we are looking at class limits
what is a class limit
we just saw in the previous definitions
that we
mentioned upper class limit and lower
class limit
right so in a continuous distribution
the class limits are called
true or actual class limits
in a continuous distribution
it is the true or actual loss limit
actual class limit
so then we just mentioned
true or actual class limit so what is a
true class limit
so true class limits are
again
sorry so true class limits are this one
is true class limits
so let me rectify that
so this will be number five actually
okay
so this will be number five that is true
class limits and then number four
we are going to define class limits
so class limits are nothing but
in the frequency table
the class interval
in a frequency table are class limits
right now what is the frequency of a
class again
bifurcate
frequency of a class
frequency of a class is the number of
tally marks opposite to a variant
right is its frequency and it is written
in the next column opposite to the tally
marks
so number of
tally marks
or the number of
times of variate
occurs in a data set is called as
frequency
and lastly
cumulative frequency
of a car plus so cumulative
frequency of a class is
nothing but
the sum of frequency of all previous
classes
right it is the sum
of frequency
of all previous classes
so isn't that easy guys if you still
have a doubt please leave a comment
below
do like the video and subscribe to our
channel i'll see you in our next video
until then bye guys keep practicing keep
flourishing"
