What are the two main groups of forecasting techniques?
Group 1: Qualitative techniques that mainly use subjective data, such as opinions from experts, clients, and consultants. They are faster to prepare and can be used in the introduction of a new product.
Group 2: Quantitative techniques that involve numerical analysis of past data, without personal opinions or guesses. A mathematical model is used. They can be divided into two main groups: techniques based on time series and techniques based on correlations.
a) Only Group 1 is correct.
b) Only Group 2 is correct.
c) Both groups are correct.

A resposta correta é a alternativa c) Ambos os grupos estão corretos. O Grupo 1 inclui técnicas qualitativas que usam dados subjetivos, como opiniões de especialistas, clientes e consultores. O Grupo 2 inclui técnicas quantitativas que envolvem análise numérica de dados passados, sem opiniões pessoais ou suposições. As técnicas quantitativas podem ser divididas em dois grupos principais: técnicas baseadas em séries temporais e técnicas baseadas em correlações.
