Twenty years ago, 48% otparents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 254 of 800 parents of children in high school felt it was a seriom problem that high school students were not being taught enough math and science, Do parents fel differently today than they did twenty years ago?

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
