In the Gapminder website, I chose to compare the infant mortality rate with the 8th grade math achievement worldwide. In the graph, there is a clear and visible diagonal trend line that starts in high infant mortality rate per 1000 births with a low math achievement, which is what I expected. As the infant mortality rate becomes lower, the math achievement becomes higher. Ghana has a high infant mortality rate (76 deaths per 1000 babies) and very low test scores (301). Ghana has the lowest test scores, yet Botswana has higher test scores (365) but a more prominent infant mortality rate (90 deaths per 1000 babies). Singapore, without surprise, has the highest test scores (596, almost 600) and the lowest infant mortality rate (2 deaths per 1000 babies). South Korea has about the same number of math achievement (595), but a higher infant mortality rate (5 deaths per 1000 babies). Within this downward diagonal line, there are a few outliers. Botswana and Bahrain lie outside the general trend. Something that surprised me was that within the range of 464-506 math achievement, there are five countries: Cyprus, Norway, Sweden, Czech Republic, and Slovenia, that all have the same number of death rates: 3 deaths per 1000 babies. I think this is interesting because for these countries, the death rate does not depend on the math achievement.
I decided to select the indicators of infant mortality rate depending on math acheivement in 8th grade for several reasons. I think that the countries that have very high test scores generally do not have a high infant mortality rate, because for one thing there are more students to take the tests, and the countries that have higher test scores a probably more well-off, so they have better health care to prevent babies from not making in to age 5. I was even surprised to see a trend because the chart is comparing infant death rate with 8th grade test scores, two different ages. Education and death rate have a lot to do with each other, because income and economy influences both of them.
I do not understand why these five countries have different test scores but all the same birth rate. A possible way to figure that out would be to do in-depth research about each country’s health-education system and economy. Also, what is interesting is that 13 years ago, those five countries were all on different spots of the chart, and now they have evened out. Something that also remains unclear is that Hungary and Lithuania have high test scores, because I always assumed that they were poor countries. But here it may not matter as much.
