‭Chapter 4: Math – Part 2‬ ‭4.1 Data Interpretation‬

‭Data‬‭plays‬‭a‬‭very‬‭vital‬‭role‬‭in‬‭our‬‭day‬‭to‬‭day‬‭life.‬‭When‬‭the‬‭data‬‭at‬‭hand‬‭is‬‭small,‬‭it‬‭is‬‭easy‬‭to‬ ‭understand,‬ ‭analyze‬ ‭and‬ ‭interpret‬ ‭in‬ ‭order‬ ‭to‬ ‭form‬‭substantial‬‭decisions.‬‭However,‬‭in‬‭case‬ ‭the‬‭data‬‭is‬‭very‬‭large,‬‭then‬‭it‬‭is‬‭generally‬‭presented‬‭in‬‭different‬‭ways,‬‭like‬‭data‬‭tables,‬‭graphs,‬ ‭bar‬ ‭charts,‬ ‭pie‬ ‭charts,‬ ‭scatterplots,‬ ‭histograms‬ ‭etc.‬ ‭In‬ ‭such‬ ‭cases,‬ ‭it‬ ‭is‬ ‭imperative‬ ‭that‬ ‭the‬ ‭user‬‭is‬‭able‬‭to‬‭understand‬‭and‬‭analyze‬‭the‬‭data‬‭precisely.‬‭The‬‭process‬‭of‬‭understanding‬‭the‬ ‭data from its represented form is known as data interpretation.‬ ‭Now‬‭we‬‭shall‬‭take‬‭each‬‭of‬‭these‬‭precise‬‭forms‬‭and‬‭understand‬‭how‬‭they‬‭can‬‭be‬‭interpreted‬ ‭using some examples.‬ ‭4.1.1 Data Tables‬ ‭Using‬‭data‬‭tables,‬‭data‬‭can‬‭be‬‭represented‬‭in‬‭a‬‭form‬‭of‬‭tabular‬‭representation.‬‭Tables‬‭can‬‭be‬ ‭single‬ ‭or‬ ‭multiple‬ ‭with‬ ‭horizontal‬ ‭rows‬ ‭and‬ ‭vertical‬ ‭columns.‬ ‭The‬ ‭data‬ ‭corresponding‬ ‭to‬ ‭each‬‭cell‬‭corresponds‬‭to‬‭its‬‭unique‬‭row‬‭and‬‭column.‬‭An‬‭instance‬‭of‬‭the‬‭data‬‭table‬‭is‬‭given‬‭as‬ ‭under:‬ ‭Sale of different models of cars (in million)‬ ‭Year‬ ‭Hyundai‬ ‭General‬ ‭Motors‬ ‭Mercedes‬ ‭Honda‬ ‭2012‬ ‭50‬ ‭76‬ ‭43‬ ‭67‬ ‭2013‬ ‭54‬ ‭74‬ ‭48‬ ‭73‬ ‭2014‬ ‭57‬ ‭69‬ ‭55‬ ‭69‬ ‭In‬‭the‬‭above‬‭table,‬‭we‬‭are‬‭given‬‭the‬‭sale‬‭of‬‭four‬‭car‬‭models‬‭for‬‭three‬‭consecutive‬‭years.‬‭From‬ ‭this data table, we can find, analysis, and interpret the following information:‬ ‭Examples‬ ‭●‬ ‭General Motors sold more models in 2012 than any other year‬ ‭●‬ ‭The sale of Hyundai increased by 8% in 2013 as compared to 2012‬ ‭●‬ ‭Mercedes witnessed maximum growth of about 14.58% in 2014 as compared to previous‬ ‭year‬
