SMS Polling

An SMS polling is a survey of public opinion for a particular sample (products, services etc). SMS polling are usually designed to represent the opinions of a population by conducting a series of questions and then extrapolating generalities in ratio or within confidence intervals. SMS Polling are sometimes considered as SMS Campaigning for sending and receiving feedbacks from the mobile users.

Polls are tracked at repeated intervals, For eg, weekly tracking poll will use the data from the past week, discarding older data.

A key benefit of tracking polls is that the trend of a tracking poll (the change over time) corrects for bias: regardless of whether a poll consistently over or underestimates opinion, the trend correctly reflects increases or decreases.

A caution is that estimating the trend is more difficult and error-prone than estimating the level – intuitively, if one estimates the change, the difference between two numbers X and Y, then one has to contend with the error in both X and Y – it is not enough to simply take the difference, as the change may be random noise.

Random noise indicates the fluctuation that occurs if we estimate the trends used for marketing the products and services on the basis of the analytical data available from the past surveys and than comparing them for changes that is about to occur on the basis of X and Y data that may have been used for estimation of results.
