Final answer:
The mode age cannot be determined without the actual SPSS output showing the frequency distribution of ages. The mode is the value that appears most frequently in a data set, and the options provided cannot be verified as correct without the SPSS data.
The correct answer is c. 21.
Step-by-step explanation:
The question presented does not contain SPSS output data for identifying the mode age. Without the actual frequency distribution data from the SPSS output, determining the mode is not possible.
The mode is the value that appears most frequently in a data set. Given the SPSS output is integral to answer this question correctly, and since it has not been provided, the mode cannot be identified from the options a) 45 & 46, b) 21 & 23, c) 21, d) 22.
To find the mode age in a dataset, one would typically look at the frequency distribution output from SPSS and identify the age values that appear most often.
The correct answer is c. 21.
