Survey results can be affected by different biases, which can make them less reliable. Here are some important points to understand:
Sampling Bias: If a survey only includes 20% of a group and that group is not random or diverse, the results might not show a true picture.
Response Bias: Sometimes, about 30% of people answering questions might give wrong answers. This can happen because they want to look good or they don’t understand the questions properly.
Nonresponse Bias: If half of the people chosen for the survey don’t reply, the results could be off. This means the final data might not truly reflect what the whole group thinks or feels.
Knowing about these biases is really important. It helps us understand survey data better and make sense of what it really means.
