Forecasting methods can be classified into two groups: qualitative and quantitative. Table 8-1 shows these two categories and their characteristics. Forecast is made subjectively by the forecaster.

Observation is the gathering of information through the five senses. ... They are explanations for observations you make. Inferences are based on your experiences and what you know. An observation about this picture is that the grass is wet.

They make use of two main types of statistics: descriptive and inferential. Descriptive statistics help psychologists get a better understanding of the general trends in their data, while inferential statistics help them draw conclusions about how their variables relate to one another.

Informal reports and formal reports have two major categories: informational and analytical reports. It's important to keep in mind that both informal and formal reports can fall into these categories (i.e., you can have an informal informational report or a formal informational report).

Here are 15 Differences between Quantitative and Qualitative Observation. Qualitative observation is a research method that examines the characteristics of research variables while quantitative observation is a research design that quantifies variables in terms of statistical and numerical value.

Explain to the class what an observation and an inference are and the difference between the two. Your explanation, for example, could be, “An observation is something you sense: taste, touch, smell, see, or hear. An inference is something you decide or think about a thing or event after you observe it.”

There are two types of statistical hypotheses. Null hypothesis. The null hypothesis, denoted by Ho, is usually the hypothesis that sample observations result purely from chance. Alternative hypothesis.

Data may be grouped into four main types based on methods for collection: observational, experimental, simulation, and derived. The type of research data you collect may affect the way you manage that data.

The data that are collected in observational research studies are often qualitative in nature but they may also be quantitative or both (mixed-methods). There are several different types of observational research designs that will be described below.

There are two types of categorical variable, nominal and ordinal. A nominal variable has no intrinsic ordering to its categories. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories. An ordinal variable has a clear ordering.

Observation is objective while inference is subjective. Observation is what one perceives or notices. On the other hand, the inference is an explanation or assumption of what one has perceived or seen. Observation is based on hands-on experience.

There are two types of quantitative variables: discrete and continuous. What does the data represent? Counts of individual items or values.

Observations can take any value between a certain set of real numbers. The value given to an observation for a continuous variable can include values as small as the instrument of measurement allows. Examples of continuous variables include height, time, age, and temperature.

With two-way ANOVA, you have one continuous dependent variable and two categorical grouping variables for the independent variables. MANOVA models several dependent variables simultaneously and you can include a variety of independent variables.
