The cards Question What is cumulative frequency? Tap to flip Answer The total of all frequencies up to a defined class: the 'running total' of frequencies. Question How are cumulative frequency graphs drawn? Tap to flip Answer As smooth curves. Question Each cumulative frequency includes all values up to which point of each group? Tap to flip Answer The upper boundary. Question What is a percentile? Tap to flip Answer A value on a scale of 100 that shows the percent of a distribution that is equal to or below it. Question Which percentile is the median? Tap to flip Answer The 50th percentile. Question Which percentile is the lower quartile? Tap to flip Answer The 25th percentile. Question Which percentile is the upper quartile? Tap to flip Answer The 75th percentile. Question What is another name for the lower quartile? Tap to flip Answer The first quartile (Q1). Question What is another name for the upper quartile? Tap to flip Answer The third quartile (Q3). Question What is the lower quartile? Tap to flip Answer The value under which 25% of data points are found when arranged in increasing order. Question To find the quartiles on a cumulative frequency graph, what must you use: the highest value on the y-axis or the total frequency? Tap to flip Answer The total frequency. Question How are values read from a cumulative frequency graph? Tap to flip Answer In the same way as a line graph. Question What does a box plot show? Tap to flip Answer The minimum and maximum value of a data set along with the three quartiles. Question How many pieces of information does a box plot need? Tap to flip Answer 5 Question What are the 5 pieces of information needed for a box plot? Tap to flip Answer Lowest value, lower quartile, median, upper quartile and highest value. Question What must you do to a list of data before finding the 5 values for a box plot? Tap to flip Answer Put it in order. Question What is the median? Tap to flip Answer The central (middle) piece of data when the data are in numerical order. Question How is the range found? Tap to flip Answer The difference between the highest and lowest values. Question What does the box part of a box plot tell us about? Tap to flip Answer The middle 50% of the data. Question When comparing box plots, what must you refer to as well as the statistics? Tap to flip Answer The context of the question. Question How is the interquartile range calculated? Tap to flip Answer Q3 − Q1. Question What does the interquartile range tell us? Tap to flip Answer How spread out the middle 50% of the data is. Question Which two measures are used to compare box plots and cumulative frequency graphs? Tap to flip Answer The median and the interquartile range. Question In a histogram, what is the area of each rectangle proportional to? Tap to flip Answer The frequency in each class. Question In a histogram, what is the width of each rectangle equal to? Tap to flip Answer The class interval. Question A histogram is a bar chart for which type of data? Tap to flip Answer Continuous data. Question Why are the bars of a histogram adjacent? Tap to flip Answer Because of the nature of the data: it is continuous. Question What is used to compare classes in a histogram with unequal class widths? Tap to flip Answer Frequency density. Question When the multiplier is 1, how is frequency density calculated? Tap to flip Answer Frequency ÷ class width. Question In a histogram, what is frequency proportional to? Tap to flip Answer The area of the bar. Question On a histogram with unequal bar widths, is the frequency density the frequency of the class? Tap to flip Answer No. Frequency density is not the frequency; the frequency is proportional to the bar's area. Question What is continuous data? Tap to flip Answer Data that can take any value within a range. Question Give one example of continuous data. Tap to flip Answer e.g. height, mass or temperature. Question What can a histogram be used to construct? Tap to flip Answer A frequency table. Question How is the arithmetic mean of a set of numerical data found? Tap to flip Answer The sum of the values divided by the number of values. Question Give one average that can be found using a histogram. Tap to flip Answer e.g. the mean or the median. Question When drawing a histogram with software, what does using the raw data allow? Tap to flip Answer The software can calculate equal bin widths easily. Question In Desmos, which brackets are used to enter raw data as a set of elements? Tap to flip Answer Square brackets [ ]. Question Why use different representations of the same data set? Tap to flip Answer They give a fuller picture.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
