1. Unbalanced sample size: an unbalanced sample size exists when the size of the sample has not been properly selected in relation to the size of the population. This can lead to bias in the results.
2. Incomplete coverage: incomplete coverage exists when not all units of the population are included in the sample, which may result in under- or over-representation of certain characteristics.
3. Non-random sampling: In non-random sampling, the elements of the population are not randomly selected, potentially biasing the results.
4. Unpredictable results: If the sample is not large enough, the results cannot be reliably predicted.
1. Inadequate target group analysis: most companies have difficulty in correctly identifying their target group. As a result, they do not know how to address their customers.
2. Unclear advertising message: if companies cannot define very clearly what advertising message they want to convey, it becomes difficult to connect with potential customers.
3. Insufficient reach: if companies are not able to send their advertising to the widest possible audience, they will attract fewer customers.
4. Insufficient budget: if companies do not have the necessary funds for advertising activities, customer acquisition will be more difficult.
5. Lack of advertising friendliness: if companies are not able to respond to the needs and expectations of their target group, they are likely to be less successful.
