What is a frequency table used for? A frequency table is a table that displays the number of times a certain value appears within the dataset, otherwise known as each value’s frequency What is one advantage of using a bar chart over a pie chart? Unlike pie charts, bar charts can be used to display the frequencies for numerous categories and are, therefore, used more often to display the results from studies with large datasets What does a frequency distribution polygon measure? Interval and ratio scales What is central tendency? Name 3 ways it can be measured. A measure that represents the middle of values within a distribution. Mean, median, and mode
How is a frequency distribution formed? When the frequency for every value in a dataset is presented What is relative frequency? The ratio of the frequency of a specific variable in relation to the total number of frequencies in the dataset What is cumulative frequency? The sum of all preceding categories Pie charts typically used to display the relative frequencies of each value or category within a qualitative or categorical data set Bar charts a set of bars is used to display the frequency of each category within a dataset Histogram a type of bar graph that uses bars to represent the frequency of quantitative data
the majority of values pile up on the left side of the distribution and the graph falls to the right creating the "tail mean arithmetic average μ population mean x̄, M sample mean Σ sum of median midpoint of the distribution mode
value with the highest frequency in a dataset outlier An extreme value that is either much smaller than, or much larger than, most of the values in a dataset variability tells you whether the scores are clustered together around the mean or whether the scores are spread out from the mean range the difference between the maximum value and the minimum value in a dataset interquartile range (IQR) represents the middle 50% of the values in a dataset = Q3-Q Box plot (box and whiskers plot) displays the variation in a set (or sets) of data by plotting the five-number summary (minimum, maximum, range, median, and interquartile range)
