Hope this helps.
There are three main types of averages.
*mean > average >
(X1+X2+X3+...+Xn) / n
*mode > the element within a set which occurs most.
{3,4,5,8,12,3,4,3,3,56}
mode = 3
*median 
{3,3,4,5,8,12,56}
median = 5
OR
{3,4,5,8,12,56}
median = 6.5

conceptual approach to limits
how are limits derived?
lameck
an entire section of calculus is devoted to that explanation.
Pitior
statistics : can be defined as the branches of mathematics that deals with the summarizing, analysing,organization and interpretation of data.
Usman
can we find Z value on calculator with out using Z table
can another way is possible ?
Maham
Well you could make a table. And as the function you use the one used at the z table
Luca
The normal function is only one way, so you can only try using different numbers until you get the probability that you have. So that is easier if you have a table
Luca
me don't know nothing about z table and don't know how to see the z value on table can you tell me please how see the value on table
Maham
The z table is the table of the standard normal distribution
Luca
You can look it up on internet, its easier than writing down the normal distribution function (with an integral) and doing a table in the calculator
Luca
yes use pnorm in r
Venkat
pnorm(2.3,mean=0,sd=1)
Venkat
do u have r software
Venkat
its with tht u will get
Venkat
z mathportal calculator
Venkat
have calculator but don't know how find z value
Maham
hey guys I'm from computer background so what are the concepts I supposed to prepare for interview in statistics
Alwin

Venkat
logistic regression
Venkat
k means clustering
Venkat
type. analytics vidya interview questions statistics
Venkat
My question is "is it only stats?"
Jameel
wer is the problem
Venkat
how find straight line equation in regression
u can find using excel
Venkat
by giving a value to x,y
Ibrokhim
first provide data
Venkat
ill solve and guve
Venkat
maham you posted data
Venkat
x:1,2,3,4,5
y:2,5,6,8,9
Maham
regredsion equation is
Venkat
reg eq is y=0.9+1.7x
Venkat
thanx venkat naveen😊

the tenth percentile for land selling at jabi is 35,000 and the nineteenth percentile for the land price in the same area is 225,what is the 10_90 percentile range
statistics is the beach of mathematics which deals with collection ,organisation, presentation, analysis and interpretation of numerical data
Saeed
oh but interpretation of data, like what and how? 🤔
Bhavani
interpretation: Think in a way that you have given a company year turnover and you have a record of 100years and data set is like (Year,Turnover). Now with that data you can interpret many thing how was the company growth, when were the losses and other things
Akash
interpretation: it is a process in which we make a decision about a population on the basis of sample data .
example: if we want to interpret the average income of employees for upcoming year so we have to interpret the income of employees on the basis of previous year's income of those employees
Saeed
thank you saeed, Akash. I understood.
Bhavani
how to remember all this formulas easy ly
Madanapalle
best way is to do as many problems as possible
Pitior
is this the only one room? or separate room for separate users? 🤔
Bhavani
Finding correlation and regression
explain statistics whether it is a science or arts or both
I would say art is a creation. A chef is an artist. They create new dishes just like the painters. I believe one who creates something new, is an artist. So, Statistics is also an art, if you know it, you can create some new formula, theory, law, etcetera. It is also Science. So yes, it is both.
Rohan
how do you use the normal distribution table when testing the hypothesis
Davia
I am sorry Davia, I cannot help you with that.
Rohan
percentages of all the possible outcomes are measured. This is so simple and bases on the questionnaire or interview schedule. It's just measuring the probability chances of high %age of the either part of the hypothesis ... dependent ..independent.
data is classified on the basis of respondents
saifuddin
how find CV(x) and CV(y)
if X: 3,7,5,4,6,9
&Y:4,9,6,4,7,8
please tell
Maham
what percent of the students would be expected to score above 95?
inferential statistics is what?
in which we make infrences (hypothsis)
asad
surpose a data set of 2,3,5,6,1,4 are given find median
fastest finger please
lucy
Mean (average) 4...
Median (middle term) 3.5..
Mode (frequency) every element in a set has 1 frequrncy
Akash
i arrange the data set in ascending order. that is, 1,2,3,4,5,6. then find the data set that falls in the middle. in this case, 3 & 4 fall in the middle. you then sum and obtain the average. that is, (3+4)/2=3.5. therefore, 3.5 is the median.
Gbenga
both of you are correct.
Joseph
how does a line graph look
King
pls who knows how line graph look like
King
line graph usually have a straight line running through axis
Dike
am new here anyone willing to orient me?
