The statement is true. A Pearson correlation of +1.00 indicates a perfect positive linear relationship between two variables, meaning that as one variable increases, the other variable also increases in a linear fashion. The Spearman correlation also measures the strength and direction of a relationship between two variables, but it does not assume a linear relationship. Instead, the Spearman correlation is based on the ranks of the observations. If two variables have a perfect positive monotonic relationship (meaning that as one variable increases, the other variable also increases, but not necessarily in a linear fashion), then the Spearman correlation would also be +1.00.
