Erika is listening to her professor discuss the details of quantum physics. She finds it difficult to concentrate during the lecture because she did not get sufficient sleep last night and is now feeling irritable and sleepy. According to the video lecture, Erika is having trouble receiving the messages sent by the professor because of noise.

What is meant by a symmetrical unimodal distribution? a. a distribution is the frequency at which a certain value of a variable is obtained during a study. a symmetric unimodal distribution is a distribution where there is one value with a larger frequency than any other and the pattern of frequencies on the left and right of this larger frequency are mirror images of each other. b. a distribution is a pattern of frequencies for the various values of a variable collected in a study. a symmetric unimodal distribution is a distribution where there is one value with a larger frequency than any other and the pattern of frequencies on the left and right of this larger frequency are mirror images of each other. c. a distribution is the frequency at which a certain value of a variable is obtained during a study. a symmetric unimodal distribution is a distribution where there is a uniform frequency, meaning the frequency of every value is same, and the pattern of frequencies on the left and right of this larger frequency are mirror images of each other.

Saade, morin, and thomas (2012) describe critical thinking as the mental processes of discernment, analysis, and evaluation applied to information in order to achieve a logical final understanding and/or judgment. describe your approach to breaking down information into component parts to better understand the characteristics of a statement, concept, or problem. how might outlining to develop understanding? how do you know when to reach beyond previous experience and seek out other sources of information to enhance your understanding of the work in front of you?
