Question

Dr. Caldwell is a forensic psychologist who works with child victims of abuse. She began to wonder whether these children have higher levels of anxiety than most children. She decided to examine this question by measuring the anxiety of 10 children who were victims of abuse, using the BAI-C. [Remember, the BAI-C is a standardized test with a mean (µ) of 50, and a standard deviation (σ) of 10, and the scores are normally distributed.] The scores for the children measured by Dr. Caldwell are as follows: BAI-C Scores 55 57 50 62 66 48 71 60 70 52 determine whether Dr. Caldwell can conclude that this sample of children has higher levels of anxiety than most children. Write the results in APA format

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
