Gender and number words: Chang, Sandhofer, and Brown (2011) wondered whether mothers used number words more, on average, with their preschool sons than with their preschool daughters. Each participating family included one mother and one child—either female or male. They speculated that early exposure to more number words might predispose children to like mathematics. They reported the following: “An independent-samples t test revealed statistically significant differences in the percentages of overall numeric speech used when interacting with boys compared with girls, t(30) = 2.40, p< .05, d = .88. That is, mothers used number terms with boys an average of 9.49% of utterances (SD = 6.78%) compared with 4.64% of utterances with girls (SD = 4.43%)” (pp. 444–445).
How many children were in the total sample? Explain how you determined this.
from given data :
Children were in total sample =60
60=(30 number of boys and 30 number of girls ).
