Question:medium

The chart above, used for the previous question, plots the cost, producer's selling price and retailer's selling price, in rupees, for 11 items prepared by a sweetshop.



Which of the following conclusion can be drawn from the diagram?

Show Hint

Check whether the x-axis is a real continuous scale before trusting the lines joining the points, and count how many genuine margins three price lines can actually give.

  • Retailer's selling price for mistisukh was more than producer's selling price for chicken titbit.
  • Difference between retailer's selling price and producer's selling price for fish kachouri was more than that of cream roll.
  • These are three types of margins for all items.
  • The three lines that connect different points, in the diagram above, are superfluous.

The Correct Option is D

Solution and Explanation

Before picking an option, ask what kind of chart this actually is. It shows three price series for 11 separate sweetshop products. A line chart is normally meant for a continuous variable such as time, where joining consecutive points shows a trend.

  1. Mistisukh vs chicken titbit: This option is really asking us to compare a point on one line for one product against a point on a different line for a totally different product. Nothing in the chart's design supports that kind of cross category, cross series comparison with confidence.
  2. Fish kachouri gap vs cream roll gap: This too needs a precise reading of two small gaps at two separate products, which is well beyond what a chart drawn this way can reliably confirm.
  3. Three margins for all items: Look again at what is actually plotted, it is cost, producer's price and retailer's price, three prices, not three margins. A margin is a difference between two prices, so at most two margins, producer's and retailer's, exist here. This statement mislabels the chart.
  4. Connecting lines are superfluous: The 11 products on the x-axis have no natural order or continuous relationship to each other, panir kachouri is not next to chicken pizza in any numeric sense. So joining them with a line, as if reading left to right shows a trend, adds a false sense of continuity. The lines do not carry any extra information beyond the individual points.

Let's summarize:

  • A chart across unrelated categories should really be a set of separate markers, not a connected line.
  • Recognising when a chart type is being misused is itself a valid, safe conclusion to draw.

So the correct conclusion is option (E), the connecting lines are superfluous.

Read the scenario and answer the question:
The upper hinge of a dataset is the median of all the values to the right of the median of the dataset in an ascending arrangement, while the lower hinge of the dataset is the median of all the values to the left of the median of the dataset in the same arrangement.
For example, consider the dataset 4, 3, 2, 6, 4, 2, 7. When arranged in the ascending order, it becomes 2, 2, 3, 4, 4, 6, 7. The median is 4 (the bold value), and hence the upper hinge is the median of 4, 6, 7, i.e., 6. Similarly, the lower hinge is 2. 
A student has surveyed thirteen of her teachers, and recorded their work experience (in integer years). Two of the values recorded by the student got smudged, and she cannot recall those values. All she remembers is that those two values were unequal, so let us write them as A and B, where A < B. The remaining eleven values, as recorded, are: 5, 6, 7, 8, 12, 16, 19, 21, 21, 27, 29. Moreover, the student also remembers the following summary measures, calculated based on all the thirteen values: 
Minimum: 2
Lower Hinge: 6.5 
Median: 12 
Upper Hinge: 21 
Maximum: 29

Read the following scenario and answer the questions that follow.
A T20 cricket match consists of two teams playing twenty overs each, numbered 1 to 20. The runs scored in any over is a non-negative integer. The run rate at the end of any over is the average runs scored up to and including that over, i.e., the run rate at the end of the kth over is the average number of runs scored in overs numbered \(1, 2, …, k,\) where \(1 \leq k \leq 20, k\) a positive integer.
The following table indicates the run rate of a team at the end of some of the overs during a T20 cricket match (correct up to 2 decimal places), where \(1 \leq N – 2 < N + 6 \leq 20\), N a positive integer. It is also known that the team did not score less than 6 runs and more than 15 runs in any over.
