For example, "The salary and housing report focuses on 1,182 survey responses from socioeconomically diverse households.". Detail the criteria you used to evaluate the data. If you borrowed criteria or evaluative methods from other researchers, cite their contributions to your report. For example, "In accordance with Smith and Goldblatt's 1999 Study of Inmate behavior, this report utilizes an adaptive behavior scale in its analysis of inmate testimony.". List any and all results that seem to indicate trends. For example, "Upon evaluating the data, this report reveals that there is a correlative trend between an individual's educational background and the likelihood that they shop at food.". Explain any recommendations your trend analysis report will make in the conclusion section of the report.

When the relationship is linear (as displayed by the scatterplot, and supported by the correlation r we can summarize the linear pattern using the least squares regression line. Remember that: The slope of the regression line tells us the average change in the response variable that results from a 1-unit increase in the explanatory variable. When biography using the regression line for predictions, you should beware of extrapolation. When examining the relationship between two variables (regardless of the case any observed relationship (association) does not imply causation, due to the possible presence of lurking variables. When we include a lurking variable in our analysis, we might need to rethink the direction of the relationship simpsons paradox. Trend analysis reports examine data in an effort to determine if certain actions or reactions occur in a patterned trend. Trend analysis reports aid workers and researchers in a multitude of fields as they attempt to make predictions about their subject matter. The summary component of a trend analysis report offers general statements about all of the components of the report as a type of overview. Writing a trend analysis summary requires you to briefly describe each component of the report and provide a summative statement regarding the findings of the report. Describe the collected data analyzed within the report. Though the specifics of the data would be analyzed in the "Data" or "Analysis" section, shredder a general statement about both the type of data gathered and the manner in which the data was gathered is important in your summary.

Eiti brief: Using, summary

Numerical measures: conditional percentages (of the response variable for each value (category) of the explanatory variable separately). Case qq: we examine the relationship using: Display: scatterplot. When describing the relationship as displayed by the scatterplot, be sure to consider: overall pattern direction, form, strength. Labeling the scatterplot (including a relevant third categorical variable in our analysis might add some insight into the nature of the relationship. In the special case that the scatterplot displays a linear relationship (and only then we supplement the scatterplot with: Numerical measures: pearsons correlation coefficient (r) measures the direction and, mba more importantly, the strength of the linear relationship. The closer r is to 1 (or -1 the stronger the positive (or negative) linear relationship. R is unitless, influenced by outliers, and should be used only as a supplement to the scatterplot.

In particular, when a distribution is approximately normal, almost all the observations (99.7) fall within 3 standard deviations of the mean. When examining the relationship between two variables, the first step is to classify the two relevant variables according to their role and type: and only then to determine the appropriate tools for summarizing the data. (We dont deal with case qc in this course). Case cq: Exploring the relationship amounts to comparing strange the distributions of the quantitative response variable for each category of the explanatory variable. To do this, we use: Display: side-by-side boxplots. Numerical measures: descriptive statistics of the response variable, for each value (category) of the explanatory variable separately. Case cc: Exploring the relationship amounts to comparing the distributions of the categorical response variable, for each category of the explanatory variable. To do this, we use: Display: two-way table.

Deviations from the pattern outliers. Numerical measures: descriptive statistics (measure of center plus measure of spread If distribution is symmetric with no outliers, use mean and standard deviation. Otherwise, use the five-number summary, in particular, median and iqr (inter-quartile range). The five-number summary and the.5(IQR) Criterion for detecting outliers are the ingredients we need to build the boxplot. Boxplots are most effective when used side-by-side for comparing distributions (see also case cq in examining relationships). In the special case of a distribution having the normal shape, the Standard deviation Rule applies. This rule tells us approximately what percent of the observations fall within 1,2, or 3 standard deviations away from the mean.

(1200 words) (Optional) summary Outside reading: Creating Data files (1200 words this summary provides a quick recap of the material in paper the Exploratory data Analysis unit. Please note that this summary does not provide complete coverage of the material, only lists the main points. The purpose of exploratory data analysis (EDA) is to convert the available data from their raw form to an informative one, in which the main features of the data are illuminated. When performing eda, we should always: use visual displays (graphs or tables) plus numerical measures. Describe the overall pattern and mention any striking deviations from that pattern. Interpret the results we find in context.

When examining the distribution of a single variable, we distinguish between a categorical variable and a quantitative variable. The distribution of a categorical variable is summarized using: Display: pie-chart or bar-chart (variation: pictogram can be misleading — beware!). Numerical measures: category (group) percentages. The distribution of a quantitative variable is summarized using: Display: histogram (or stemplot, mainly for small data sets). When describing the distribution as displayed by the histogram, we should describe the: overall pattern shape, center, spread.

Enter the formula in the next column one line higher. We select a range of values including a column with input values and a formula A3:B12. Go to the "data" tab. Open the "What-if Analysis" tool. We click the "Data table" button.


There are two fields in the opened dialog box. Since we create a table with one input we enter the address only in the field "Column input cell. If the input values are in lines (not in columns we will enter the cells number in the field "Row input cell: " and click. When using the features Excel, to analyze the enterprise activity, we use information from the balance sheet and income statement. Each user creates his own form, which reflects the features of the company and important information for decision-making). (Optional) Outside reading: look at the data!
