The researcher is using _____ observation. • answer**Strategies & Designs --$400**• This type of research design can be useful for studying unusual clinical cases such as brain injuries. • answer**Strategies & Designs --$500**• A researcher systematically varies the amount of caffeine in cola (0, 10, and 20 mg) and observes that his participants’ anxiety levels increase as caffeine amount increases. The 0-mg condition is called the __________. • answer**Frequency Distributions--$100**• The simplest frequency distribution consists of these two columns. • answer**Frequency Distributions --$200**• The shape of a _____ distribution is perfectly symmetrical. • answer**Frequency Distributions --$300**• This is the appropriate type of chart (or visual) for discrete data. • answer**Frequency Distributions --$400**• These two types of charts appropriately represent data from continuous variables. • answer**Frequency Distributions --$500**• A mathematical procedure for estimating a value that is located between two known values. • answer**Descriptive Stats--$100**• A statistical measure that determines a single value that accurately describes the typical score of a distribution. • answer**Descriptive Stats--$200**• This measure of central tendency is the score at the 50th percentile. • answer**Descriptive Stats --$300**• This measure of variability measures the average distance between scores and the mean. • answer**Descriptive Stats --$400**• This measures the average of the squared distances from the mean. • answer**Descriptive Stats --$500**• In order to calculate this, take the square root of the population variance. • answer**Grab Bag--$100**• The type of correlation that indicates an inverse relationship between two variables. • answer**Grab Bag--$200**• In statistical formulas, N represents ______________. • answer**Grab Bag--$300**• The only appropriate measure of central tendency for data measured on a nominal scale. • answer**Grab Bag--$400**• Percentile ranks correspond to the values in the ______ column of a frequency distribution • answer**Grab Bag--$500**• The sum of the deviations from the mean always equal this. • answer**Validity--$100**• A: What is external validity? • Back to board**Validity--$200**• A: What is internal validity? • Back to board**Validity--$300**• A: What is confounded? • Back to board**Validity--$400**• A: What is extraneous? • Back to board**Validity--$500**• A: What is internal validity and external validity? • Back to board**Strategies & Designs--$100**• A: What is descriptive? • Back to board**Strategies & Designs--$200**• A: What is correlational? • Back to board**Strategies & Designs--$300**• A: What is participant observation? • Back to board**Strategies & Designs--$400**• A: What is the case study? • Back to board**Strategies & Designs--$500**• A: What is the placebo control group? • Back to board**Frequency Distributions--$100**• A: What is score (X) and frequency (f) ? • Back to board**Frequency Distributions--$200**• A: What is normal? • Back to board**Frequency Distributions--$300**• A: What is a bar graph? • Back to board**Frequency Distributions--$400**• A: What are histograms and frequency distribution polygons? • Back to board**Frequency Distributions--$500**• A: What is interpolation? • Back to board**Descriptive Stats--$100**• A: What is central tendency? • Back to board**Descriptive Stats--$200**• A: What is the median? • Back to board**Descriptive Stats--$300**• A: What is the standard deviation? • Back to board**Descriptive Stats--$400**• A: What is the variance (or mean square)? • Back to board**Descriptive Stats--$500**• A: What is population standard deviation? • Back to board**Grab Bag--$100**• A: What is negative? • Back to board**Grab Bag--$200**• A: What is the number of participants/scores in the population? • Back to board**Grab Bag--$300**• A: What is the mode? • Back to board
