In this study, the questionnaires were distributed to the students in UiTM Puncak Alam by using the simple random sampling. The researchers distributed the questionnaires randomly to any students of Faculty Business and Management. DATA COLLECTION METHOD Primary and secondary data is used in this study as the data collection methods. a) Primary Data Primary

The value of y when x = 0 The predicted value of y, given a specific x value The slope of the equation The y-intercept bias can occur in sampling. Bias refers to _____________________. the use of cluster sampling instead of stratified random sampling the division of the population into overlapping groups the tendency of a sample statistic to systematically

concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. In business and medical research, sampling is widely used for gathering information about a population. Random sampling: In this technique, each member of the population has an equal chance of being selected as subject. The entire process of sampling is done in a single step with each subject selected independently of the other members of the population.

cheaper to collect as well as more time efficient as compared to primary source data. The nature of the data above is relevant to what Hayward is searching for. Knowing the spending trend of the entire population on the specific country could be very useful to determine if it is the right time/ market to venture in. ________________________________________________________________________________________________________ We would recommend probability samples design to non-probability samples

uniformly at random between string length [1, l] Two new strings are created by swapping all characters between two positons (See Figure 4-4). This crossover gives genetic algorithm much of their power. With crossover, beneficial mutations on two parents can be combined immediately when they reproduce. Mutation, on the other hand, randomly changes a bit in an individual from 0 to1 or vice versa, thereby introducing new material into the knowledge base. This operator is assigned a very low percentage

Sampling section, an activity-time study for a secretary was used. From the activity-time study, the percentage spent in each activity category was computed by using three different methods: using all the data, using a sequential pattern, and using a random time for every ten minute time period. When using all the data, the total minutes spent on each

predominant belief among real estate professionals is that appraisal error is random. This belief materially influences investor attitudes toward portfolio management and the valuation process itself. Lack of understanding of the relative magnitudes of random and nonrandom components of total appraisal error has consequences for optimal portfolio strategies. For example, investors who deem the bulk of total appraisal error to be random may reasonably conclude that error in estimates is beyond their control
