A scatter diagram visually represents the relationship between two variables, allowing you to observe patterns, trends, and potential correlations. By examining the shape of the data points, you can determine if the relationship is linear, quadratic, or exhibits another form. For instance, if the points roughly form a straight line, a linear regression may be appropriate; if they curve, a polynomial regression could be better suited. Additionally, the presence of clusters or outliers can inform the choice of regression model and its complexity.
in general regression model the dependent variable is continuous and independent variable is discrete type. in genral regression model the variables are linearly related. in logistic regression model the response varaible must be categorical type. the relation ship between the response and explonatory variables is non-linear.
The scatter plot is the most commonly used type of graph in science because it effectively displays the relationship between two quantitative variables, allowing researchers to observe patterns, trends, and correlations. By plotting individual data points, it facilitates the identification of outliers and the assessment of data dispersion. Additionally, scatter plots can help in fitting regression lines, aiding in predictive analysis and hypothesis testing. This versatility makes them an essential tool for data visualization in scientific research.

To use regression equations on a TI-86 calculator, first input your data by selecting the "Data" menu and entering your x and y values into the appropriate lists. Once your data is entered, access the "Calculate" menu and choose the desired regression type (e.g., linear, quadratic). After selecting the regression type, the calculator will output the regression equation and key statistics. You can then use this equation for predictions or further analysis.
All you have to do is to select the values you want to have compared with Excel. Then click on Insert on the top, then Scatter, then Scatter with only markers. After this, you can give name to the axises, but then in the Layout section you have to select the regression type of the trendline as well.
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
