This study was conducted to explore whether perception of money by preschool age children is influenced by their family wealth. This was investigated by testing how the children would recall the size of a coin, with the assumption that the size recalled related to the value placed on the coin.
To conduct the study, three local day-care facilities specializing in preschool age children were randomly selected. Consent forms were sent home to the parents of the kids, which also asked parents for their average yearly household income. Since everyone from the three selected facilities was used in the study, this is random sampling. The income data collected was what type of data (categorical or quantitative)?
From the parents who consented, the children were divided into two groups: those whose family income was greater than $40,000, and those whose family income was less than $40,000.
Each child was asked to draw a nickel. The resulting circle diameter was then measured. When the shape drawn was not a perfect circle, the largest and smallest diameters were averaged. If the researcher found the mean of all the coin diameter data, would that be a statistic or a parameter?
The gender of each child was also collected. The gender data was what type of data?
Since we are not imposing an intervention or treatment on the children, this is not an
It is hypothesized that children from lower income families would draw larger coins than children from higher income families.
