  2. 3 research methods used in behavioral science -- Answer ✔✔
  1. experimental design
  2. quasi experimental design method
  3. correctional method
  1. _______________ uses manipulation, randomization, and comparison/control to ensure enough control to allow researchers to draw cause-and-effect conclusions -- Answer ✔✔ experimental design
  2. ______________ is structured similar to an experiment but lacks randomization and/or a comparison/control group -- Answer ✔✔ quasi experimental design
  3. __________________ used to measure pairs of scores for each individual and examine the relationship between variables -- Answer ✔✔ correctional method
  4. 4 scales of measurement -- Answer ✔✔
  • nominal
  • ordinal
  • interval
  • ratio
  1. _________ are typically coded (ie. seasons, months, sex) -- Answer ✔✔ nominal scales
  1. displays the frequency of categories or whole units when the number of different values collected is small and displays the data in intervals
  • each interval is equidistant
  • no interval overlaps
  • the degree of accuracy for each interval is the same as in the original data -- Answer ✔✔ simply frequency distribution for grouped data
  1. steps to constructing frequency distribution -- Answer ✔✔
  • step 1: find the real range
  • step 2: find the interval width
  • step 3: construct the frequency distribution
  1. ____________ a summary display that distributes the sum of frequencies across a series of intervals
  • add from the bottom up when discussing the data in terms of "less than" or "at or below" a certain value
  • add from top down when discussing the data in terms of "greater than" or "at or above" a certain value or "at least" -- Answer ✔✔ cumulative frequency
  1. ___________ is a summary display that distributes the proportion of scores in each interval -- Answer ✔✔ relative frequency
  2. divide the frequency of each interval by the total number of score counted
  • reported when summarizing large
  • multiple each relative frequency by 100 to convert into percentages
  • both summary displays convey the same information -- Answer ✔✔ computing relative frequency
  1. ____________ is a summary display for the sum of relative frequencies from the top down or the bottom up
  • can be converted to percent by multiplying the _______ in each interval by 100
  • can be distributed as percentile ranks, which indicate the percentage of scores at or below a given score -- Answer ✔✔ cumulative relative frequency
  1. __________ measures of the relative position of individuals or scores within a larger distribution -- Answer ✔✔ percentiles
  2. ___________ is the value of an individual or score within a larger distribution -- Answer ✔✔ percentile point
  3. how to find percentile point in a cumulative percent distribution -- Answer ✔✔
  • step 1: identify the interval within which a specified percentile point falls
  • step 2: identify the real range for the interval identified
  • step 3: find the position of the percentile point within the interval
  • step 4: identify the percentile point
  1. ____________ is a graphical display used to summarize the frequency of continuous data distributed in numeric intervals (grouped)
  • constructed by distributing the intervals along the x axis nd listing the frequencies of scores on the y axis -- Answer ✔✔ histogram
  1. ____________ is used to summarize discrete and categorical data
  • bars separate to indicate discrete units or classes -- Answer ✔✔ bar chart
