Question

1- What are the advantages and disadvantages for using doughnut chart?

2- What type of insights can you gain from a contingency table that contains three variables that you cannot gain from a contingency table that contains two variables?

Answer 1

Answer :

(1).

The advantages  for using doughnut chart : -

it is anything but difficult to frame and change

the qualities can be fluctuated and embedded

the diagram can have diverse hues and shapes

the readings are straightforward

A straightforward and straightforward picture.

It speaks to information outwardly as a partial piece of an entire, which can be a viable specialized instrument for the even ignorant gathering of people.

It empowers the group of onlookers to see an information examination initially to make a prompt investigation or to comprehend data rapidly.

The requirement for perusers to look at or measure fundamental numbers themselves can be evacuated by utilizing this outline.

To stress directs you need toward make, you can control bits of information in the pie diagram.

Disadvantages for using doughnut chart :-

In the event that such a large number of bits of information are utilized, pie graph turns out to be less viable.

They themselves may end up swarmed and difficult to peruse if there are such a large number of bits of information, and regardless of whether you include information names and numbers may not help here.

You need an arrangement to think about numerous sets as this graph just speaks to one informational index.

To examine and absorb data rapidly, this may make it increasingly troublesome for perusers

As the peruser needs to factor in points and think about non-adjoining cuts, it has its issues in looking at the information cuts.

To settle on choices dependent on visual effect as opposed to information examination drives peruser to make off base determinations

Negative Pie/positive Pie can't be comprehended until I float the pointer on the pie. So when Negative information present, pie outline is a terrible alternative

three variables that you cannot gain from a contingency table that contains two variables

1. An essential of any exploration ponder is the decision of indicator and

control factors.

2. Except if we incorporate applicable factors in the investigation, result will have

restricted convenience.

3. In study connection between a reaction variable and an illustrative

variable, we should control covariates that can impact that

relationship

4. For example, we are contemplating impacts of un involved smoking-the consequences for

non-smoker of living with a smoker. We may look at lung malignant growth

rates between non-smokers whose companions smoke and non-smokers

whose companions don't smoke.

5. In doing as such, we should control for age, workplace,

financial status, or different elements that may relate both to

regardless of whether one's life partner smokers and to whether one has lung disease.
