Explain the difference between simple correlation and multiple correlation. Simple and multiple correlations are two classifications of correlation. However, Correlation is simple if it concerns relationship between two variables while it is multiple if it concerns the relationship among three or more variables. Explain four (4) levels of measurement and give one (1) example each
A. Nominal Scale: Nominal data are counted data. Each individual can only be a member of mutually exclusive category and not the other. All members of each category include notionally, gender, socioeconomic status, occupation, role, religious affiliation etc. Numbers are often used at the nominal level, but only in order to identify the categories. The
What is a scale of measurement? Scale of measurement entails the method used for translation of observation into numbers. For measurement to be carried out in statistics, objects and events has to be assigned numerals according to certain scales or rules. Starting with variables, some rules are then used to determine how these variables will
1. Random Sampling: Random sampling involves selecting a subset of individuals from the entire population in such a way that each member of the population has an equal chance of being chosen. This technique ensures that the sample is representative of the population, reducing the potential for bias. In educational research, a random sample
The steps are as follows: Calculate the mean (average) of the scores. Subtract the mean from each score, square the result. Calculate the mean of those squared differences. Take the square root of that mean to get the standard deviation. Step 1: The mean is indeed 5.5. Step 2: Subtract the mean from each
Science and Mathematics Education: The conference recognized the importance of a strong foundation in science and mathematics. These subjects were seen as essential for fostering critical thinking, problem-solving skills, and a deeper understanding of the natural world. Emphasis was placed on inquiry-based learning and practical applications of scientific principles. Language Education: Language education was highlighted

Write briefly on the following terms : (a) A one-tailed test. (b) Systematic Sampling (c) A Two-tailed test (d) Cluster sampling (e) accidental/ haphazard sampling (a) A One-Tailed Test: A one-tailed test, also known as a one-sided test, is a statistical hypothesis test that examines whether a sample’s result falls significantly above
Educational Statistics refer to the quantitative data that is collected, analyzed, and interpreted to gain insights into various aspects of the education system. These statistics play a pivotal role in shaping educational policies, improving teaching methodologies, and enhancing the overall quality of education. Key Aspects of Educational Statistics: Data Collection: Educational statistics involve
Samples Find the mean and the mode of the following set of data 1.) 2,3,5,7,9,9,10,11,14,and 18 2.) 3,5,8,10,12,15,and 16 3.) 2,3,4,4, 5,5,7,7,7,and 9 Solution 1. Data set: 2, 3, 5, 7, 9, 9, 10, 11, 14, 18 Mean = (2 + 3 + 5 + 7 + 9 + 9 + 10 + 11
Mean: The mean, also known as the average, is the sum of all values divided by the total number of values. It gives us an idea of the typical value in a dataset. For instance, if we have test scores of 10 students: 75, 80, 85, 90, 95, 70, 75, 80, 85, 90, the mean
Explain five (5) main objectives of indigenous or traditional education in Nigeria. The latent aims of the indigenous system of education as observed by Fafunwa (1974), which provided the bases, and process of training in the traditional education system are: A. To develop the child’s latent physical skills: B. To develop character: C. To
Johann Friedrich Herbart, a prominent educational theorist, introduced a pedagogical approach that emphasized a systematic and structured process for teaching. In 1906, he laid out five formal steps, often referred to as the “Herbartian Five-Step Method,” which aimed to facilitate effective instruction and student engagement. These steps were designed to guide teachers in organizing lessons
THE NATURE OF ROMAN EDUCATIONAL SYSTEM BEFORE THE ADVENT OF THE GREEKS. Before the Greeks began to influence Roman education, the early Roman educational system was primarily informal and practical. Education was imparted within the family and focused on teaching essential life skills such as
