The researcher is interested in how people change on the personality dimension of neuroticism over the years. He administered the neuroticism scale to a random sample of 100 ten-year olds in 1980. He administered the same test to the same group in 1990 when they were 20 years old, then again in 2000 when they were 30 years old, then again in 2010 when they were 40 years old. He plans to administer the test one more time in 2020 when they will be 50 years old. He believes that their neuroticism scores will gradually decrease over the decades. What statistical test should he use to analyze the data? a. Independent Samples t-test b. Chi Square Test of Independence c. One Way ANOVA d. Paired t-test e. Repeated Measures ANOVA
