Question

Researchers studied 600 people and matched their personality type to when in the year they were born. They discovered that the number of people with a"cyclothymic" temperament, characterized byrapid, frequent swings between sad and cheerfulmoods, was significantly lower in those born in the spring. The study also found that those born in the summer were less likely to be excessively positive, while those born in winter were more likely to be depressive. Complete parts(a) through(c) below.(a)What is the research question the study addresses?(b)What is the sample?(c)What type of variable is the season in which you were born?

Answer 1

The research question is whether temperament is correlated with birth season. The study's sample includes 600 individuals, and the season of birth is treated as a categorical variable.

Step-by-step explanation:

The study conducted by researchers aims to address the following aspects:

The research question the study addresses is whether there is a correlation between an individual's temperament and their birth season. Specifically, it explores if cyclothymic temperament is less common in individuals born in spring, if those born in the summer are less likely to be excessively positive, and if those born in winter are more prone to depressive temperaments.

The sample of the study consists of 600 individuals whose personalities were evaluated and matched to their birth seasons to examine the pattern of temperament variation.

The season in which an individual is born is considered a categorical variable, as it is used to group participants into distinct categories, such as spring, summer, fall, and winter, without any inherent numerical value.

Answer 2

a) One possible research question is: Does the season in wich people is born have any effect on their personality tipes?

b) The sample is: the 600 people analysed in the study. Remember that the sample is a representative selection form the whole population, this to reduce costs and time. In this case researchers could not afford to analyse millions of people so they chose 600.

c) The season in wich you were born is the independent variable. This means that the researcher can't do anything to interfer with it. This kind of variable is the one that affects the dependent one.
