Some agencies do random sampling of constituencies, both state-wise or pan-India. Or, the random sampling can be of the electorate as well, being it in whichever parameter such as age, sex, caste, region etc.

Some agencies opt for systematic sampling as well, where they carefully chart out all the variables. However, systematic sampling is practically not possible when it comes to predicting the results of the world’s largest demography. Hence, a majority of agencies prefer random sampling.

There are several techniques that are used by scores of organisations such as Cube Law (where seat-share is an important factor), or Index of Opposition Unity (where a party’s vote share assists its ally), or Probabilistic Count (which helps in deciphering large data).

What are the challenges in carrying out Exit Polls?

There are a lot of challenges that one has to face while conducting an election Exit Poll. The toughest of them all is to convert the vote percentage to the number of seats. Also, factors like voter turnout, vote share, proper sampling, adequate sample size, rural-urban divide are some of the important factors. Any miscalculation, missing, or over-calculation of any data type or size reflects poor results.

Should you believe in Exit Polls in India?

Well, the answer is a bit complicated one, i.e. not completely. Gone are the days when Exit Polls used to be bang-on precise with the actual election results. However, they do give a trend or show a projection as to what the real results will be on the judgment day.

Nonetheless, when we talk about 2004 Lok Sabha Elections, 2012 Uttar Pradesh Assembly Elections, 2014 Lok Sabha Elections, 2015 Delhi Assembly Elections, or even 2018 Karnataka Assembly Elections – the results were very different from what the exit polls had actually predicted.

So, it depends on the agencies and the methods they have used to forecast the election results. They can be right, they can be completely wrong too; nonetheless, they are able to at least predict the trend in the right direction most number of times.

The 2019 Lok Sabha Elections took place in a seven-phased manner, starting from April 10. The last phase of the Elections 2019 will take place on May 19, after which the results will be declared on May 23.
