Alternative hypothesis

dependent variable is the subjects Calorie/menu choices. The researcher has posed three Research Question, and has identified a null and alternative hypothesis for each. RQ1: Are young Millennials’ menu choices on low-Calories items correlated with different menu designs applying menu psychology? Tian has created a null hypothesis and alternate hypothesis for each factor studied when considering the menu design to include the serial position effect, the gaze motion theory and the salience…

The null hypothesis of this test is that the past p values of X are not helpful to predict Y (X does not Granger cause Y). The alternative hypothesis is that the past p values of X are useful to predict Y (X Granger causes Y). p is the lag length of the Granger causality test and the results of the test depend on the chosen lag…

number of breaths also decreased. The mean of the average number of breaths is 69.24. The number of breaths in the study ranged from 16 to 135 breaths per minute. The null hypothesis, that the temperature of the water has no effect on the number of breaths per minute, can be rejected. The results support the alternative hypothesis. The control fish number of breaths per minutes remained constant in the study. Goldfish are ectotherms animals; the goldfish body temperature depends on the…

areas, (Nores et al., 2013). The primary pollinator of bougainvilleas is the bee, but other weather factors such as wind can affect pollination in bougainvilleas. The hypothesis of this experiment is that the weather in which a bougainvillea is, will affect how many pollinators the plant will encounter on a given day. The null hypothesis is that the weather has no effect on the amount of pollinators that visit the bougainvillea encounters. The reason these questions are important is because they…

When conducting a hypothesis test for the difference between two means it’s essentially called a two sample t-test. According to Dr. Mirabella (2011, p. 5-2) states that, “In each case you can conduct a t-test for independent means to determine if a significant difference exists.” Furthermore, we’re conducting this test to see if there is an overlapping or if there is clearly a difference among the GPAs for men and women. In our case we are comparing the GPAs for a sample of men and a sample…

important to look for prerequisites that cover the whole landscape and demarcate it into sensible divisions. Reiss (2015) argues that a theory of evidence should be informative about how to gather evidence and when to be justified in believing a hypothesis on the basis of evidence in non-ideal scenarios as well as ideal ones. He puts forward four desiderata for a theory of evidence. It should: (1) be a theory of support; (2) be a theory of warrant; (3) apply to non-ideal scenarios; and (4)…

A case study reflecting on observations of children’s schematic interests. In the paper I will be discussing the history and theories of schemas. I will include observations on a child’s schematic interests and my role as the practitioner. A Schema is a pattern of repeatable behaviour into which experiences are assimilated and that are gradually coordinated. (Athey, 1990:37) Children’s patterns are influenced through their genetically pre-determined biological development and the socio-cultural…

behavior. Modern scientific method hypothetico-deductivism, which is the process of making conclusions from the examination of hypotheses. However, Popper said that even if the results of the experiment coincide with the primordial hypothesis, it does not mean that the hypothesis is proved. Here, Blaikie added induction, which is the process of logical conclusion from observation on the basis of the transition from specific facts to general. The purpose of inductive approach is to identify rules…

For many years, relationship has been a major factor with the interaction of human beings. There are various ways a person can have a relationship with another individual. For instance, a person can have a professional, intimate or even a friendly relationship with one another. It was always evident that there were different among individuals however, the question that many had wondered was the vital role that these relationships had played with individuals. American psychologist Harry Harlow,…

This current semester I had the opportunity to do a project that allowed me to visit one of my friend’s family to observe her three girls. I observed her three daughters to see how each one of them is developing. I was fortunate enough to have three different ages that are at different stages of life. One just started school, the other one is not in school yet and the youngest was born less than a year ago. It really opened my eyes to how two year differences can really impact the stage the…
